Electrical Terms & Theory

The path followed by flowing electrons from the point where they leave the electricity generating facility (source) until they return to it in a closed loop or path.

• Circuit
• Conductor
• Amp
• Watts

Materials with loosely held electrons in the outer shell of the atom that allow electrons to move freely in a controlled manner.

• Circuit
• Conductor
• Amp
• Watts

Measure of electrical current flow. When 6.28 quintillion electrons pass any particular point in a circuit in one second.

• Circuit
• Conductor
• Amp
• Watts

The rate at which electrical current is measured. Describes the amount of light, heat or work that is done.

• Circuit
• Conductor
• Amp
• Watts

Overcurrent protection device that senses electrical imbalance on the line or load side of the circuit and shuts the circuit down to protect persons from electrical shock. You probably have one in the bathroom and kitchen.

• GFCI
• Cable
• Grounding Conductor
• Duplex Receptacle

Two or more conductors grouped together in a single unit covered by a protective sheath.

• GFCI
• Cable
• Grounding Conductor
• Duplex Receptacle

Conductor that transmits electrical current to the earth to prevent a short circuit.

• GFCI

• Duplex Receptacle

The ungrounded conductor that carries the current to the load.

• Hot
• Neutral
