Circuits and Electricity

Front

What is a circuit?

Back

A circuit is a complete path through which electricity can flow, typically including a power source, wires, and a load (like a light bulb).

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is a conductor?

Back

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

What is an insulator?

Back

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

Front

What happens when a switch is open?

Back

When a switch is open, the circuit is incomplete, and electricity cannot flow, so the devices (like lights) do not work.

Front

What happens when a switch is closed?

Back

When a switch is closed, the circuit is complete, allowing electricity to flow and powering the devices.

Front

What is a light bulb in a circuit?

Back

A light bulb is a load in a circuit that converts electrical energy into light energy.

Front

What is the function of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path, 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 components are connected across common points, allowing multiple paths for electricity to flow.
