The Circuit

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What are the two main types of circuits?

Back

The two main types of circuits are series circuits and parallel circuits.

Front

What is a series circuit?

Back

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

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

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.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily, such as rubber or glass.

Front

What is a switch?

Back

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

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electric current is interrupted, and devices in the circuit do not operate.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electric current can flow freely, allowing devices in the circuit to operate.
