Current is the rate at which electric charge flows past a point in a circuit. In other words, the current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
This slide is special for master students (MIBS & MIFB) in UUM. Also useful for readers who are interested in the topic of contemporary Islamic banking.

5. CIRCUITSIn order for electricity to flow we need
Power source
Closed circuit
There are two type of circuits we will
explore
Series circuit
Parallel circuit
6. SIMPLE CIRCUITS• Series circuit
–All in a row
–1 path for electricity
–1 light goes out and
the circuit is broken
• Parallel circuit
– Many paths for
electricity
– 1 light goes out and
the others stay on
7. SERIES CIRCUIT
In a series circuit there is only one path
for the electrons to flow
In other words all the components are in
series with each other
Because there is only one path each
charge will go through each resistor
9. SERIES CIRCUIT
•A series circuit is one that has more than one
resistor, but only one path through which the
electricity (electrons) flows. From one end of the
cell (battery), the electrons move along one
path with NO branches, through the resistors, to
the other end of the cell. All the components in
a series circuit are connected end-to-end.
10. RESISTOR
• A resistor in a circuit is anything that uses some of
the power from the cell. In the example below, the
resistors are the bulbs. In a series circuit, the
components are arranged in a line, one after the
other.
11.
12. • Each time there is damage (break) in any one of the resistors
the entire circuit will not function. For example, if one light bulb
goes out, all the other lights will go off because the electricity
path in the broken bulb is cut off.
• Do you put Christmas lights on the trees at home during
Christmas? If the lights are in a series circuit, one burned out
bulb will keep all the lights off. That is one disadvantage of
series circuits. One advantage though is that you will always
know if there is a break in a series circuit.
• If there are many bulbs in a circuit with a battery (cell), it is very
likely that the light will be dimmer because many resistors are
acting on the same voltage of power from the battery.
13. "1. THE SAME CURRENT FLOWS THROUGH
EACH PART OF A SERIES CIRCUIT."
• In a series circuit, the amperage at any
point in the circuit is the same. This will
help in calculating circuit values using
Ohm's Law.
• You will notice from the diagram that 1
amp continually flows through the
circuit. We will get to the calculations in
a moment.
14. "2. THE TOTAL RESISTANCE OF A SERIES
CIRCUIT IS EQUAL TO THE SUM OF
INDIVIDUAL RESISTANCES."
• In a series circuit you will need to calculate
the total resistance of the circuit in order to
figure out the amperage. This is done by
adding up the individual values of each
component in series.
In this example we have three resistors. To
calculate the total resistance we use the
formula:
• RT = R1 + R2 + R3
• 2 + 2 + 3 = 7 Ohms
15. CALCULATING RESISTANCE IN
SERIES CIRCUITS
The rule for
calculating Series
Circuits is to…
Add up the values of
each individual in the
series.
R1 + R2 + R3…
5 + 5 + 10
20 Ω (ohms)
16. • Now with these two rules we can learn how to calculate
the amperage of a circuit.
Remember from Ohms Law that I = V / R. Now we will
modify this slightly and say I = V / R total.
• Lets follow our example figure:
• RT = R1 + R2 + R3
• RT = 7 Ohms
• I = V / RT
• I = 12V / 7 Ohms
• I = 1.7 Amp
• If we had the amperage already and wanted to know the
voltage, we can use Ohm's Law as well.
• V = I x R total
• V = 1.7 A x 7 Ohms
• V = 12 V
17. "Voltage Drops"
• Before we go any further let's define what a "voltage drop"
A voltage drop is the amount the voltage lowers when
crossing a component from the negative side to the positive
side in a series circuit. If you placed a multimeter across a
resistor, the voltage drop would be the amount of voltage
you are reading. This is pictured with the red arrow in the
diagram.
• Say a battery is supplying 12 volts to a circuit of two resistors; each having
a value of 5 Ohms. According to the previous rules we figure out the
resistance.:
• RT = R1 + R2 = 5 = 5 = 10 Ohms
• Next we calculate the amperage in the circuit:
• I = V / RT = 12V / 10 Ohms = 1.2 Amp
• Now that we know the amperage for the circuit (remember the
does not change in a series circuit) we can calculate what the voltage
drops across each resistor is using Ohm's Law (V = I x R).
• V1 = 1.2A x 5 Ohms = 6 V
18. "3. VOLTAGE APPLIED TO A SERIES
CIRCUIT IS EQUAL TO THE SUM OF THE
INDIVIDUAL VOLTAGE DROPS."
• This simply means that the voltage drops have to add up to
the voltage coming from the battery or batteries.
• V total = V1 + V2 + V3 ...
• In our example above, this means that
• 6V + 6V = 12V.
19. "4. THE VOLTAGE DROP ACROSS A
RESISTOR IN A SERIES CIRCUIT IS
DIRECTLY PROPORTIONAL TO THE SIZE OF
THE RESISTOR."
•This is what we described in the
Voltage Drop section above.
•Voltage drop = Current times
Resistor size.
20. "5. IF THE CIRCUIT IS BROKEN AT ANY
POINT, NO CURRENT WILL FLOW."
•The best way to
illustrate this is with a
string of light bulbs. If
one is burnt out, the
whole thing stops
working.
21. ON THIS PAGE, WE’LL OUTLINE THE THREE
PRINCIPLES YOU SHOULD UNDERSTAND
REGARDING SERIES CIRCUITS:
•Current: The amount of current is the same
through any component in a series circuit.
•Resistance: The total resistance of any series
circuit is equal to the sum of the individual
resistances.
•Voltage: The supply voltage in a series circuit is
equal to the sum of the individual voltage
22.
23. •With a single-battery, single-resistor circuit, we
could easily calculate any quantity because they
all applied to the same two points in the circuit:
38. •REVIEW:
•Components in a series circuit share the same
current: ITotal = I1 = I2 = . . . In
•The total resistance in a series circuit is equal to
the sum of the individual resistances: RTotal =
R1 + R2 + . . . Rn
•Total voltage in a series circuit is equal to the
sum of the individual voltage drops ETotal = E1 +
E2 + . . . En
Editor's Notes
1.A power source is a source of power. Most commonly the type of power referred to is: Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time.2. Closed circuit means a complete electrical connection around which current flows or circulates. When you have a series of electrical wires connecting to each other and completing a circuit so that current travels from one end of the circle to the other, this is an example of a closed circuit.
A series circuit is one with all the loads in a row. There is only ONE path for the electricity to flow. If this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.
Since points 1 and 2 are connected together with the wire of negligible resistance, as are points 3 and 4, we can say that point 1 is electrically common to point 2, and that point 3 is electrically common to point 4. Since we know we have 9 volts of electromotive force between points 1 and 4 (directly across the battery), and since point 2 is common to point 1 and point 3 common to point 4, we must also have 9 volts between points 2 and 3 (directly across the resistor).
Therefore, we can apply Ohm’s Law (I = E/R) to the current through the resistor, because we know the voltage (E) across the resistor and the resistance (R) of that resistor. All terms (E, I, R) apply to the same two points in the circuit, to that same resistor, so we can use the Ohm’s Law formula with no reservation.
In circuits containing more than one resistor, we must be careful in how we apply Ohm’s Law. In the three-resistor example circuit below, we know that we have 9 volts between points 1 and 4, which is the amount of electromotive force driving the current through the series combination of R1, R2, and R3. However, we cannot take the value of 9 volts and divide it by 3k, 10k or 5k Ω to try to find a current value, because we don’t know how much voltage is across any one of those resistors, individually.
For R1, Ohm’s Law will relate the amount of voltage across R1 with the current through R1, given R1‘s resistance, 3kΩ:
But, since we don’t know the voltage across R1 (only the total voltage supplied by the battery across the three-resistor series combination) and we don’t know the current through R1, we can’t do any calculations with either formula. The same goes for R2 and R3: we can apply the Ohm’s Law equations if and only if all terms are representative of their respective quantities between the same two points in the circuit.
So what can we do? We know the voltage of the source (9 volts) applied across the series combination of R1, R2, and R3, and we know the resistance of each resistor, but since those quantities aren’t in the same context, we can’t use Ohm’s Law to determine the circuit current. If only we knew what the total resistance was for the circuit: then we could calculate the total current with our figure for total voltage (I=E/R).
Combining Multiple Resistors into an Equivalent Total Resistor
This brings us to the second principle of series circuits:
The total resistance of any series circuit is equal to the sum of the individual resistances.
This should make intuitive sense: the more resistors in series that the current must flow through, the more difficult it will be for the current to flow.
In the example problem, we had a 3 kΩ, 10 kΩ, and 5 kΩ resistors in series, giving us a total resistance of 18 kΩ:
In essence, we’ve calculated the equivalent resistance of R1, R2, and R3 combined. Knowing this, we could redraw the circuit with a single equivalent resistor representing the series combination of R1, R2, and R3:
Calculating Circuit Current Using Ohm’s Law
Now we have all the necessary information to calculate circuit current because we have the voltage between points 1 and 4 (9 volts) and the resistance between points 1 and 4 (18 kΩ):
Calculating Component Voltages Using Ohm’s Law
Knowing that current is equal through all components of a series circuit (and we just determined the current through the battery), we can go back to our original circuit schematic and note the current through each component:
Now that we know the amount of current through each resistor, we can use Ohm’s Law to determine the voltage drop across each one (applying Ohm’s Law in its proper context):
Notice the voltage drops across each resistor, and how the sum of the voltage drops (1.5 + 5 + 2.5) is equal to the battery (supply) voltage: 9 volts.
This is the third principle of series circuits:
The supply voltage in a series circuit is equal to the sum of the individual voltage drops.
