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 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 circuit where the components are connected across common points or junctions, allowing current to flow through multiple paths.

Front

What is an electric current?

Back

Electric current is the flow of electric charge, typically measured in amperes (A).

Front

What is voltage?

Back

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

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 resists the flow of electric current, 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 battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to provide power to a circuit.
