What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source (like a battery), conductors (like wires), and a load (like a light bulb).

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides a voltage to push electric current through a circuit.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy when electric current passes through it.

Front

What is a switch?

Back

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

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electric current to flow and powering the connected devices.

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electric current and turning off the connected devices.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

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

Front

What is resistance in an electric circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current flows in a circuit.

Front

What is a conductor?

Back

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