Electrical Guided Notes Vocabulary Flashcards

Vocabulary flashcards generated from the lecture notes on electrical fundamentals, defining essential terms like voltage, current, resistance, AC, DC, and basic circuit concepts.

Conductor

A material that allows electrons to easily flow through it.

Insulator

A material with high electrical resistance.

Current

The amount of electrons flowing, measured in Amps (also known as Amperes).

Voltage

The pressure or force behind electrical flow, measured in Volts.

Resistance

The friction of electrical flow, measured in Ohms.

Short Circuit

A circuit that lacks practical-use resistance.

Alternating Current (AC)

Electric current used in power lines and home outlets where the current and direction are always changing.

Direct Current (DC)

A steady current flowing in one direction, commonly used in battery-powered devices and cars.

Circuit

A system that basically includes a voltage source, a load, and usually wires.

Closed Circuit

A circuit that allows current to travel from and return to the battery or voltage source.
