Electrical Terms

5. The electrical potential difference between two points in a circuit.
6. A semiconductor device that allows current to flow in one direction while blocking it in the opposite direction, used in rectifying electrical signals.
7. Motor An electric motor that turns the engine over to start the vehicle by engaging with the flywheel.
8. Plug A device that ignites the air-fuel mixture in the engine cylinder by producing an electrical spark.
9. Harness A bundle of electrical wires and connectors that transmit power and signals to different parts of the vehicle.
11. An electrical generator that charges the vehicle's battery and provides power to run electrical systems when the engine is running.

1. System The components that generate and deliver the high-voltage electrical spark needed to ignite the fuel in the engine cylinders.
2. A device that stores electrical energy and supplies it to the vehicle's electrical system for starting the engine and powering various components.
3. A safety device that interrupts the flow of electrical current in the event of a circuit overload or short circuit to prevent damage or fires.
4. The opposition to the flow of electrical current in a circuit, measured in ohms (Ω).
10. An electromagnetic switch that uses a small electrical signal to control a larger electrical current, often used to control various components in the vehicle.
