Electric Circuits

Front

What is an electric circuit?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows electric current to pass 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 electric current to pass through it easily, such as rubber or plastic.

Front

What is a complete circuit?

Back

A complete circuit is a closed path that allows electricity to flow from the power source, through the load, and back to the power source.

Front

What happens in a circuit when the switch is open?

Back

When the switch is open, the circuit is incomplete, and electric current cannot flow, so devices like light bulbs will not light up.

Front

What happens in a circuit when the switch is closed?

Back

When the switch is closed, the circuit is complete, allowing electric current to flow and devices like light bulbs to light up.

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 a circuit, controlling the flow of electric current.

Front

What is a series circuit?

Back

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