Energy

4. Plant materials and animal waste used especially as a source of fuel.
7. The flow of electrical power or charge.
9. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit
10. The rate at which work is performed or energy is expended.
13. A result of a force moving an object a certain distance.
14. The net transfer of electric charge (electron movement along a path) per unit of time.
15. The unit of electric current in the meter-kilogram-second system of units. Referred to as amp and symbolized as A.
16. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work.

1. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
2. The unit of electric resistance in the meter-kilogram-second system of units. Symbolized as Ω.
3. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body.
5. A dynamo or similar machine for converting mechanical energy into electricity.
6. The rotating member of an electrical machine.
8. The opposition that a device or material offers to the flow of direct current.
11. The unit of potential difference symbolized as V.
12. A machine for producing power in which a wheel or rotor is made to revolve by a fast-moving flow of water, steam, gas, or air.
