Electrical Terminology
- Nameplate: Indicates voltage needed, required frequency, and watts consumed by an appliance.
- Electrical Current: Movement of electricity along a path known as a conductor.
- Load: Technical term for any electrically powered appliance.
- Conductor: Material that easily allows electricity to flow through it.
Electrical Units
- Amp: Unit of electrical strength.
- Volt: Unit of electrical pressure.
- Ohm: Unit of electrical resistance.
- Watt: Measurement of electrical energy consumption.
Electrical Equipment
