1. the flow of electricity in an electronic circuit, It is measured in amperes (A).
2. a device that is used to adjust the resistance in an electric circuit.
4. Material that do allow electricity to pass through them.
6. measurement device used to measure voltage in electrical circuits or electronic devices.
8. This heats up when an electric current passes through it and produces light as a result.
12. the quantity of charge which passes in a conductor per unit of time.
13. the unit of measure for electrical current.
15. circuit an electrical path that branches so that the current divides and only part of it flows through any branch.
