This document provides instructions for applying the superposition theorem to solve circuits with multiple voltage sources. Students are asked to use Multisim simulation software to build two circuits, measure currents, and apply the superposition theorem to solve for specific branch currents. The procedure involves shorting voltage sources one at a time to determine the individual source contributions, then combining the contributions using algebraic addition or subtraction to find the total branch currents. Screenshots of Multisim measurements are required to verify the calculated results.

In analyzing a circuit using Kirchhoff's circuit laws, one can either do nodal analysis using Kirchhoff's current law (KCL) or mesh analysis using Kirchhoff's voltage law (KVL). Nodal analysis writes an equation at each electrical node, requiring that the branch currents incident at a node must sum to zero.

ELC 131 Lab 4: Series-Parallel and Bridge Circuits
Introduction: Virtually all electronic products are filled with components that are connected both in series and in parallel to form circuits that are coupled, or combined, in order to perform a desired function. The key component to analyzing series-parallel circuits is the ablility to recognize which components are connected in series and which components are connected in parallel.
Objectives: Upon completion of this lab exercise the student will be able to:
1. Identify which components are connected in series and which components are connected in parallel in a series-parallel circuit; calculate the total resistance of a simple series-parallel circuit.
2. Calculate and measure the current flow through and the voltage dropped across any component in a simple series-parallel circuit.
3. Calculate the node voltages of a ladder network.
4. Recognize a circuit as being a bridge configuration; determine the value of resistance that will balance a bridge circuit when the resistance of three arms is given.
5. Describe an operation of a bridge circuit used to sense a change in temperature.

Section 1: Series-Parallel Circuits
Before beginning the analysis of a series-parallel circuit, you must recognize which components are connected in parallel and which components are connected in series. Refer to the circuit of Figure 1. Resistors R2 and R3 are connected in parallel. Resistor R1 is in series with both the parallel combination of R2 and R3 and the source.
The current supplied by the source, IT, flows through R1. IT splits into two branch currents, IR2 and IR3, at node A. These two branch currents combine a node B and flow back into the source.
Figure 1: Series-Parallel Circuit Example
Calculating the total resistance is the first step in analyzing a series-parallel circuit. To find the total resistance of a series-parallel circuit, the circuit has to be simplified, one part at a time, until a simple series or a simple parallel circuit remains.
For the circuit of Figure 1, first the resistance of R2 in parallel with R3 is calculated as follows:
Now, the series-parallel circuit can be reduced to the simple series circuit shown in Figure 2.
Figure 2: Circuit of Figure 1 Reduced to a Series Circuit
The total resistance of the circuit of Figure 1 is calculated as follows:
The current supplied by the source is calculated using Ohm’s law as follows:
The voltage dropped across each of the resistors is calculated using Ohm’s law as follows:
The source current, IT, flows through R1.
The current through R2 is calculated .

Policy Change Proposal Section II
Introduction
The proposed policy change is meant to improve the effectiveness of public laws and regulations and even give information on the public use of funds. Further, it will address the practices of the private sector employment that affects the ability of people to work and make their living above the poverty line and this mostly applies to the youths, unmarried dependent adults. The proposal is meant to make the public policy more inclusive, collaborative and responsive to the interests of the ordinary citizen so as to prepare them for their future life.
From the proposed amendment, there are measurable goals that will determine the level of success of the policy change proposal and this will include: First, by the end of the year we expect 60% of unmarried adult children to be independent and live an economically viable lifestyle. Second, by the end of 2018, the rate of poverty to reduce by 19% since the country will be composed of economically productive youths. Lastly, we expect the employment rate in the country t.

In the wake of the terrorist attacks in September 2001, the 9/11 Commission recommended that the U.S. Intelligence Community (USIC) find a way to improve information sharing of terrorism-related intelligence at all three levels of government (local, state, and federal). The USIC’s answer to this recommendation was the creation of intelligence
fusion centers
.
Since the creation of these intelligence fusion centers, there has been much controversy because of the large amounts of personal information secretly collected and shared within the U.S. intelligence and law enforcement communities. In addition, some critics argue that in the years since their creation, fusion centers and the law enforcement entities affiliated with them have moved away from their original purpose and instead have utilized federal grants and resources to fight local crime.
Assignment Guidelines
In 5–6 paragraphs, address the following:
In your opinion, how effective are U.S. fusion centers? Explain.
Do you feel that the creation of fusion centers has improved information sharing of terrorism-related information at all three levels of government? Why or why not?
Do you feel that fusion centers have ultimately moved away from their intended purpose? Why or why not?
Are fusion centers now being used as a local law enforcement tool to help fight local crime? Why or why not?

In the United States, managed care is becoming an increasingly popul.docxmodi11
In the United States, managed care is becoming an increasingly popular method of administering healthcare. It influences the clinical behavior of providers, as it combines the payment and delivery of healthcare into a single system, the purpose of which is to control the cost, quality, and access of healthcare services for a single bracket of health plan enrollees (Scutchfield, Lee, & Patton, 1997).
Yet, managed care often evokes strong or negative reactions from healthcare providers because they are paid a fixed amount for treating their patients, regardless of the actual cost, which may influence their level of efficiency. This can challenge the relationships between doctors and patients (Claxton, Rae, Panchal, Damico, & Lundy, 2012; Sekhri, 2000).
Research managed care's inception and study some examples. Be sure to investigate the perspectives about managed care from the vantage of both healthcare providers and patients. You can use the following keywords for your research—United States managed care, history of managed care, and managed care timeline.
Based on your research, answer the following questions in a 8- to 10-page Microsoft Word document:
What are the positive and negative aspects of managed care? Analyze the benefits and the risks for both providers and patients, and how providers should choose among managed care contracts. Conclude with your analysis and recommendations for managed care health plans. Your response should include answers to the following questions:
Summarize the history of when, how, and why managed care was developed.
Define and discuss each type of managed care organization (MCO)—health maintenance organization (HMO), preferred provider organization (PPO), and point of sale (POS).
Explain the positive and negative aspects, respectively, of managed care organization from the provider's point of view—a physician and a healthcare facility—and from a patient's point of view.
Explain the three types of incentives for providers for efficiency in the delivery of healthcare services. Explain who bears the financial risk—the provider, the patient, or the managed care organization.
Offer your recommendations, to accept or decline, for patients considering managed care health plans, with your rationale for each.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

7. Superposition Theorem - Components
The superposition theorem extends the use of Ohm’s Law to
circuits with multiple voltage or current sources.
In order to apply the superposition, all the components must be
linear, or “Ohmic”, meaning that the component obeys Ohm’s
Law
Yes: Resistors, Capacitors, Inductors
No: Transistors, semiconductor diodes, and electron tubes,
Operational Amplifiers. Such components are never bilateral
and seldom linear.
8. Superposition Theorem
The Superposition is useful when we have more than one
Voltage Source or more than one Current Source
We will only consider Voltage Sources in this course
9. This analysis is done by calculating the current contributed by
each source, and then adding or subtracting (i.e. taking the
Superposition) the currents contributed by each source
10. 7-2: Current Dividers with
Two Parallel Resistances
This slide applies to the special case where we have just 2
resistors in parallel
IT is divided into individual branch currents.
Each branch current is inversely proportional to the branch
resistance value.
For two (and only 2) resistors, R1 and R2, in parallel:
13. 5
Determine The Currents going through each resistors
Last time, we analyzed this circuit and determined the total
current was 2 Amps. All of the current flows through R1 and
R2, so the current in those resistors must be 2 Amps

2A
14. Determine The Currents going through each resistors
At Point A, the current splits into two branches. The resistance
of Branch 1 is R5 = 10Ω. Last time, we determined the
resistance of branch 2 was also 10Ω
2A

15. Determine The Currents going through each resistors
2 Amps enters node A. We can use the current divider to
determine the current leaving node A.

Determine The Currents going through each resistors
Since 1 Amp goes into each branch, we know the currents
through R5 and R6 are each 1 Amp. Use the current divider to
find the current through the 12 Ohm resistors.

Step 1 - Direction of Current through R3
The total current leaves V1 from the positive (top) terminal and
passes through R1. It then splits into two branches. The
current passing through R3 is going in in the downward
direction.

39. Lab #3 Worksheet
Watch the Video on eCampus. For each of the Series-Parallel
circuits:
1) Build the circuit in Multisim Live and “measure” the Total
Current and the current in each of the
parallel branches.
2) Calculate the Total Resistance, RT, of the Circuit.
3) Using RT, use Ohm's Law to calculate the total current, IT.
4) Use IT current divider formula to determine the current in
each of the resistors. Draw the
40. direction of each current on the diagram.

1. Find the current magnitude and direction in each resistor
using the current divider formula.
(Remember: The current is the same for resistors that are in
series with each other.)
2. Find the current magnitude and direction in each resistor
using the current divider formula. Hint:
First find the current through R2. The current will first branch
at node A. The first branch has
resistance R2. The 2nd branch resistance will be the combined
resistance of resistors 4-9. Trace a
path from point A to point B to determine which of theses
resistors are in series and which are in
parallel and calculate accordingly.

ENGR2105 Lab3 Superposition Theorem
Student Name __________________________________
Objectives:
To solve a network containing resistors and multiple power
sources. To learn the use of a
computer to solve electrical circuits and compare calculated
results with simulated results.
42. Materials:
Computer to access Multisim Live. Calculator.
Background Information:
The Superposition Theorem can be used to solve circuits
including resistors and multiple
sources. It can be applied only when all the components are
linear and passive. The main idea is
that the effect of all power sources can be found by summing
the effects of each power source
individually.
You are expected to show all the formulas and calculations
needed to find the answers. These
can be handwritten in the worksheets. Take screenshots of each
of the Multisim measurements
that you take.
