Electric Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electricity to flow from a power source, through conductors, and back to the power source.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

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

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the components are connected one after another, so the same current flows through all of them.

Front

What is a parallel circuit?

Back

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

Front

What is the function of a switch in a circuit?

Back

A switch is used to turn the flow of electricity on or off in a circuit.

Front

Why is plastic used to cover electrical wires?

Back

Plastic is used to cover electrical wires to provide insulation, making it safe to handle and preventing short circuits.

Front

What happens if a circuit is open?

Back

If a circuit is open, the flow of electricity is interrupted, and devices connected to the circuit will not work.

Front

What is a battery?

Back

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

Front

What is voltage?

Back

Voltage is the measure of electrical potential difference between two points in a circuit, which pushes the current through.
