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.

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. |
