Circuits

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and devices like lightbulbs to operate.

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

What is the role of a battery in a circuit?

Back

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

Front

What happens if a lightbulb is broken in a circuit?

Back

If a lightbulb is broken, it creates an open circuit, preventing electricity from flowing and other bulbs from lighting up.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (stopping) or closing (allowing) the circuit.

Front

What does it mean for a circuit to be open?

Back

An open circuit means that the path for electricity is broken, preventing current from flowing.

Front

What does it mean for a circuit to be closed?

Back

A closed circuit means that the path for electricity is complete, allowing current to flow.
