What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, allowing current to flow through multiple paths.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component in a series circuit fails, the entire circuit is broken and all components stop working.

Front

What happens to the current in a parallel circuit if one component fails?

Back

If one component in a parallel circuit fails, the other components continue to operate because there are multiple paths for the current.

Front

What is electrical resistance?

Back

Electrical resistance is a measure of the opposition to the flow of electric current in a material.

Front

What is the unit of electrical resistance?

Back

The unit of electrical resistance is the ohm (Ω).

Front

What is an electrical switch?

Back

An electrical switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What is alternating current (AC)?

Back

Alternating current (AC) is an electric current that reverses direction periodically, as opposed to direct current (DC) which flows in one direction.

Front

What is direct current (DC)?

Back

Direct current (DC) is an electric current that flows in one direction only.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.
