Across
- 2. any of a class of devices that convert chemical energy directly into electrical energy
- 6. one in which every component is arranged in a series connection
- 9. the “pressure” that pushes electricity
- 10. the ability to move heat or electricity from one place to another
- 11. the flow of electrical power or charge
- 12. a device, which converts chemical energy into electrical energy
- 13. Unit of electric current
- 14. the act of fighting against something that is attacking you, or refusing to accept something
- 16. A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.
- 17. 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. an electrical component that breaks or closes an electric circuit
Down
- 1. the resistance of a wire of that substance with unit length and unit area of cross-section
- 3. the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light
- 4. an electrical safety device having a metal wire or strip that melts and interrupts the circuit when the current becomes too strong.
- 5. a graphical representation of an electrical circuit.
- 7. the materials or substances which allow electricity to flow through them
- 8. an electrical path that branches so that the current divides and only part of it flows through any branch
- 12. a complete circular path that electricity flows through
- 15. the rate at which electrons flow past a point in a complete electrical circuit.
- 17. the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.
