What is a circuit?

Back

A circuit is a closed path through which electric current flows. It consists of a power source, conductors, and a load.

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 type of circuit where the components are connected end-to-end, so the current flows through each component one after the other.

Front

What is a parallel circuit?

Back

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

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 is a load in a circuit?

Back

A load is any device that uses electrical energy to perform work, such as a light bulb or a motor.

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 work.

Front

What happens when a circuit is closed?

Back

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