AC DC

Front

Current that does NOT reverse direction is called ____.

Back

Direct current (DC) is the type of electrical current that flows in one direction only.

Front

An electric current is defined as the flow of ? through a conductor.

Back

Electrons are the particles that flow through a conductor to create an electric current.

Front

What is the unit of measurement for resistance?

Back

Ohms (Ω) is the unit used to measure electrical resistance.

Front

Which is NOT a conductor?

Back

Examples of materials that are NOT conductors include rubber, glass, and wood.

Front

Which is NOT an insulator?

Back

Examples of materials that are NOT insulators include copper, aluminum, and silver.

Front

What is alternating current (AC)?

Back

Alternating current (AC) is an electric current that reverses direction periodically.

Front

What is the difference between AC and DC?

Back

AC (Alternating Current) changes direction periodically, while DC (Direct Current) flows in one direction.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow from a power source to a load and back.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow easily, such as metals like copper and aluminum.
