Across
- 3. An electric current flowing in one direction only.
- 5. These are automatically operated electrical switches that protect electrical circuits from overloading or short circuiting.
- 8. Material that does not allow charge or heat to pass through it easily.
- 9. An electromotive force or potential difference expressed in volts.
- 10. An electrical component that protects circuits and electrical devices from overload by melting when the current becomes too high.
- 11. A stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
Down
- 1. An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
- 2. An electrical quantity that measures how the device or material reduces the electric current flow through it.
- 4. The potential difference (or voltage) of a supply is a measure of the energy given to the charge carriers in a circuit, units volts (V).
- 6. Cause injury or death by an electric shock.
- 7. A flow of electricity which results from the ordered directional movement of electrically charged particles.
