Basics of Electricity
Across
- 2. is quantitatively equal to the resistance R of a specimen such as a wire
- 3. the pressure from an electrical circuit's power source that pushes charged electrons
- 4. a unit of device that converts chemical energy into electrical energy
- 5. Conductivity is a measure of the ability of water to pass an electrical current
- 6. a substance or material that allows electricity to flow through it
- 10. formula used to calculate the relationship between voltage, current and resistance in an electrical
- 12. has two or more paths for current to flow through
- 15. any device used to interrupt the flow of electrons in a circuit
- 16. an electrical safety device that operates to provide overcurrent protection of an electrical circuit
- 17. Circuit one in which all circuit elements are arranged in a single path
- 18. a device that converts chemical energy contained within its active materials directly into
- 19. the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit
Down
- 1. a graphical representation of an electrical circuit
- 4. closed loop that electrons can travel in
- 7. electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
- 8. is the unit of electric potential, electric potential difference (voltage), and electromotive
- 9. transfers energy from the battery to the circuit components
- 11. the unit of measure for electrical current.
- 13. a measure of the opposition to current flow in an electrical circuit
- 14. materials with a high resistivity
