Electrical circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is a series circuit?

Back

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

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning the current cannot flow due to a break in the path.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow uninterrupted.

Front

What is a power source in a circuit?

Back

A power source provides the energy needed for the current to flow, commonly a battery or power supply.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, often described as what 'slows down' electrons.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, preventing it from passing through, such as rubber or glass.

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.
