Safety

Avoid electrical shock, and load centers are high voltage areas.

2

Voltage

Is the electricalforce , whicg causes current to flow in a circuit. Measured in volts.

3

Current

is the movement of electrical charge through the electronic circuit. Measured in Amperes.

4

Resistance

causes an opposition to the flow of electricity in a circuit. Controls the amount of voltage/amoerage in a circuit. Measure in ohms.

5

Hertz

an electrical unit of frequency equal to one cycle per second. Measured in Hertz.
