3 way switch
A 3-way switch allows lighting to be turned on or off from two separate locations. It uses three conductors to connect two SPDT switches to a light fixture or bulb. The light will be off when both switches are in the same position (both position 1 or both position 2) and on when the switches are in opposite positions, with one in position 1 and the other in position 2 or vice versa.
BASIC TRANSFORMER CALCULATIONS
Transformers play an important role in the distribution of electricity-Understanding how transformers are used to alter the voltage of a supply is very important, as they form an important part of all electrical appliances, mobile phone, TV, radio, you just name it.

Lecture on wire splicing and termination
Wire Splicing
A wire spice is when two pieces of electrical wire are taken and join them together with a crimp, butt-splice, or heat shrink to make a complete electrical connection.
Importance of Wire Splicing
The Splicing or jointing is required since the wires are manufactured in 100 metres lengths and the total length of wire used for house wiring may be more than 100 metres.
The jointing conductors and wires should always be carried out at outlets i.e. in switches,ceiling roses using the looping in system or in junction boxes.
Splicing should never be done in conduit runs but sometimes necessary when repairing old works.

Basics of Electronics
Resistors are used to limit current or divide voltage and can generate heat. Capacitors store energy in the form of charge and are measured in Farads. Diodes only conduct current in one direction, while transistors can amplify or switch electronic signals and have emitter, base, and collector terminals.
1 Conduit PEC.pptx
Electrical conduit comes in both metallic and non-metallic varieties and protects electrical wiring from damage. Metallic types include EMT (thin-walled steel), IMC (thicker walls than EMT), and RMC (thick threaded walls), while non-metallic types are ENT (thin corrugated plastic) and RNC (rigid plastic). Conduits are chosen based on their protection, flexibility, corrosion resistance, and cost for the installation. Metallic conduit provides better protection but is more expensive to install, while non-metallic is cheaper but offers less impact resistance.

Resistance lesson 1
Resistance is the opposition to electric current flow in a circuit. Resistors are components that provide resistance and are used to control current. There are different types of resistors like fixed resistors, variable resistors called rheostats, and light-dependent resistors that change resistance based on light levels. Resistance depends on factors like the material, length, thickness, and temperature of the resistor. Materials range from good conductors like copper with low resistance to insulators like wood with very high resistance.
Circuits1
Electricity flows through circuits in a complete path called a closed circuit. Flashlights use batteries to power a light bulb through a closed circuit that is opened and closed by a switch. Circuits require a power source, conductor, and load, with electricity only flowing when the path is complete. Common conductors include metals, while insulators prevent electricity from flowing through materials like plastic or rubber. Circuits can be connected in series with one switch controlling all components, or parallel with individual switches for each component. Standard symbols are used to diagram electrical circuits.
Circuits
An electric circuit is a closed path that allows electrons to flow from an energy source and back. A closed circuit allows continuous electron flow, while an open circuit interrupts flow. Common circuit components include batteries, wires, switches, bulbs and resistors. Circuit diagrams use symbols to represent components and visualize connections before building real circuits. Series circuits have a single current path, so adding resistors increases total resistance and dims all bulbs. Parallel circuits provide multiple paths, so adding resistors decreases total resistance despite each path's resistance increasing.

Circuits
A circuit is a closed loop that allows electric charges to flow continuously from the positive terminal of a battery or other energy source, through external components, and back to the negative terminal. For a circuit to work, it must include an energy source that establishes a potential difference to drive the movement of charges along a conducting loop between the source's terminals. Common circuit components include batteries, wires, light bulbs, and resistors, with circuits classified as either series or parallel depending on how the components are connected.

An electric circuit is formed with electrons that flow from a voltage source like a battery through a conductor like wire to a load and back to the source, completing the circuit. Key components include a power source, wires, and a load such as a light bulb. Circuits can be open or closed, with closed circuits allowing continuous current flow and open circuits interrupting flow. Circuit types include parallel, series, and series-parallel configurations.
Electric Field, Electric Circuit and Electric Current
This document defines and describes electric fields, electric current, and electrical circuits. It discusses how electric fields create forces on charged particles, how current is the flow of electric charge in a circuit, and how circuits can be connected in series or parallel. Components like batteries, bulbs, switches, and wires are explained. Diagrams illustrate key concepts like open versus closed circuits, series versus parallel connections, and circuit symbols.
Electricity
The document discusses electricity and electrical circuits. It introduces Benjamin Franklin and Thomas Edison as important figures in the history of electricity. It defines electricity as the flow of electrons along a wire, which is called a current. It explains the components of electrical circuits including cells/batteries, switches, bulbs, wires, voltmeters, ammeters, resistors, motors, and more. It discusses the differences between series and parallel circuits and how current and voltage are measured in circuits.
Sci 9 Lesson 5 May 11 - Electric Current
The document discusses electric circuits and their components. It defines an electric circuit as a complete pathway that allows electrons to flow and an electric load as any device that transforms electrical energy. It explains that a basic electric circuit consists of four main components: a source of electrical energy, a conductor to allow electron flow, a load to transform the energy, and an optional switch. It also discusses electric current, its measurement in amps, and how circuit diagrams depict circuits using standardized symbols.
Intro to electricity
This document contains notes from a lesson on electricity. Some key points include:
- Electricity is the flow of electrons in a circuit powered by a battery or other energy source. An electric current is measured in amps and is the rate of flow of electric charges.
- Circuits can be arranged in series or parallel. A series circuit has components connected one after the other, while a parallel circuit splits into two or more branches.
- Other concepts covered include electric fields, voltage, resistance, and the relationships between current, voltage, power, and resistance defined by Ohm's law. Hands-on modeling of electric circuits used "pretzels" representing electrons.

- 2. ALWAYS REMEMBER!! WHEN DEALING WITH ELECTRICITY SAFETY FIRST ALL THE TIME
- 3. SCHEMATIC DIAGRAM Is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. The symbolic elements are arranged to be more easily interpreted by the viewer.
- 5. PICTORIAL DIAGRAM is a sketch of electrical circuit that shows the external appearance of each component. It is much like a photograph of the circuit and uses simple images of parts. The simplest of all the diagram
- 7. ELECTRICAL CIRCUITS Is a path in which electrons from a voltage or current source flow Complete circuit is composed of source, load and a path
- 9. TWO FORMS OF ELECTRICAL POWER (SOURCE) ALTERNATING CURRENT DIRECT CURRENT
- 11. CLOSED CIRCUITS An electrical circuit through which current can flow in an uninterrupted path. Continuous path through which current can flow
- 14. OPEN CIRCUIT This is a type of circuit in which there is NO current flow When you open the switch or turned it off it becomes open circuit and becomes closed circuit when turned on.
- 16. SHORT CIRCUIT A type of circuit that allows a current to travel along an unintended path. This result in excessive amount of current flow, which causes fire or explosion .
- 17. SERIES CIRCUITS
- 18. SERIES CIRCUITS The current through series component is equal The voltage drops across each components in the circuit sum to the source voltage. Also, in a series circuit, all components of the same type may be combined to result in an equipment value.
- 19. Is that the amount of current is the same through the component in the circuit. This is because there is only one path for electrons to flow in a series circuit, and because free electrons flow through conductors. A device is connected in a manner such that there is only one pathway by which charge can transverse the external circuits
- 22. PARALLEL CIRCUITS The voltage across every parallel component is equal. Has more than one resistor and gets its name from having multiple paths to move along.
- 23. Charges can move through any several paths. Is one that has two or more paths for the electricity to flow, the loads are parallel to each other.
- 25. Difference between Series and Parallel Circuits SERIES CIRCUITS SIMILARITY PARALLEL CIRCUITS One pathway Converts electrical energy to light, heat, sound, etc. Two or more path Current same anywhere in the circuit Current splits passes through pathways One bulb is busted, circuit incomplete Voltages across are equal Brightness of the bulb is less One bulb is busted, Circuit is still complete
- 26. Cite some importance of Series and Parallel Circuits in the households.
- 27. MULTIPLE CHOICE 1. Which of the following statement does NOT describe a series circuits? A. Resistance adds up draws less current B. Brightness of bulbs are less C. Current splits- passes through pathways adds up again D. Battery last longer 2. Which of these statements BEST describes a parallel circuits? A. Battery life is shorter B. Currents splits-passes through pathways and adds up again C. A closed circuit in which current divides into two or more paths by recombining to complete the circuit D. Brings more electricity than series circuit
