Across
- 2. Source of electric power
- 6. the circuit elements are arranged in a single path.
- 9. the “pressure” that pushes electricity.
- 10. a measure of a solution's ability to conduct electricity
- 11. the flow of electrical power or charge
- 12. The fundamental building block of a battery
- 13. Unit of electric current
- 14. a measure of the opposition to current flow in an electrical circuit.
- 16. A material or an object that does not easily allow heat, electricity, light, or sound to pass through it
- 17. a measurement of resistance between two points of a conductor when a constant potential difference of one volt (V) is applied to those points and a current of one ampere (A) is produced.
- 18. a small control for an electrical device which you use to turn the device on or off.
Down
- 1. a property that describes the extent to which a material opposes the flow of electric current through it.
- 3. a unit of electrical potential difference and electromotive force equal to the difference in potential between two points in a conducting wire carrying a constant current of one ampere when the power used between these two points is equal to one watt.
- 4. an electrical safety device that operates to provide overcurrent protection of an electrical circuit.
- 5. a simplified drawing of an electrical circuit.
- 7. a substance or material that allows electricity to flow through it.
- 8. has two or more paths for current to flow through
- 12. comprises several essential components that work together to facilitate the flow of current and power devices.
- 15. a flow of electrical charge carriers, usually electrons or electron-deficient atoms.
- 17. the electric current through a conductor between two points is directly proportional to the voltage across the two points.
