Basic Electrical Concepts

Front

What is an electrical conductor?

Back

A material that allows the flow of electrical current.

Front

What is an electrical insulator?

Back

A material through which it is very hard to conduct an electric current.

Front

What is electrical continuity?

Back

A continuous path for the flow of an electrical current.

Front

What is voltage?

Back

The pressure, or difference in electric potential between two points, which causes current to flow in a circuit.

Front

What is a multimeter?

Back

An instrument used to measure voltage, current, and resistance in an electrical circuit.

Front

What are electrons?

Back

Subatomic particles with a negative charge that flow through a conductor to create electricity.

Front

What is a circuit?

Back

A closed loop that allows current to flow from a voltage source to a connected load.

Front

What is a battery's anode?

Back

The source of electrons in a device, labeled the negative side of a battery.

Front

What is a battery's cathode?

Back

The side where electrons are going, labeled the positive side of a battery.

Front

What is static electricity?

Back

An imbalance of electrons due to friction, that can be discharged.
