Basic Principles of Electrical Circuits - JSS1 Basic technology Lesson Note

• Voltage (V): Voltage, measured in volts (V), represents the electrical potential difference between two points in a circuit. It acts as the driving force that propels electric charges through a conductor, analogous to water pressure in a pipe.
• Current (I): Current, measured in amperes (A), denotes the flow of electric charge through a conductor over time. It quantifies the rate of electron flow in a circuit, similar to the flow rate of water in a pipe.
• Resistance (R): Resistance, measured in ohms (Ω), signifies the opposition to electric current flow in a material or component. It determines the degree to which a material or component impedes electron flow, akin to the narrowing of a pipe restricting water flow.

Comprehending these fundamental principles of electricity is essential for designing, analysing, and troubleshooting electrical circuits and systems.
