Z

 Z A Demonstration of how something works.
1 volt   A In electrical engineering, electrical potential difference is the voltage present between two points,
2 ampere   B A unit measuring the strength of an electrical current, based on the number of electrons transferring past a given point per second.
3 watt   C A device that is used to convert AC current into DC current by only allowing current to flow in one direction.
4 ohm   D The opposition against the free transfer of electrons in a conductor. Measured in ohms.
5 resistance,   E A completed, low-resistance circuit that allows electrons to follow a shorter, unintended path back to the power source rather than follow the longer path that goes through the load. Occurs when bare wires touch each other; often results from worn insulation.
6 potential difference   F To connect any part of an electrical wiring system to the ground or to another conducting body, such as a metal water pipe or a metal rod driven into the earth.
7 rectifier   G A unit of measurement for electrical resistance to a current.

Ohm's law states that the pressure of  one volt will cause a current of one ampere to flow through a resistance of one ohm
(Voltage= Current X Resistance)
This simple formula shows the relationship between volts, amperes, and resistance in any electric circuit.
 Ohms Link 
8  rheostat   H Unit that measures electrical power at the point where it is used in a circuit. One watt of power equals one volt of pressure times one ampere of current. 
9 conductor   I A loop-shaped path through which electric current travels from the source through some device using electricity (the load), such as a light bulb, and back to the source.
10 ground   J A substance or device through which electricity passes. Most metals are good conductors of electricity -- that is, they allow electricity to travel through them with little resistance.
11 circuit   K A rheostat is a simple device used to control the electrical current in a circuit by inserting a length of high-resistance wire or other resistive material. The resistance of a rheostat is measured in ohms.

Another name for a rheostat is a potentiometer.  Where would you see one?? Volume controls on older TVs and radios. 
12 short circuit.   L A unit of potential difference, or a unit of measurement of electrical pressure or force.
