Circuits

Front

What is a circuit?

Back

A circuit is a closed path through which electricity flows.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

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

Front

What happens when a switch is open in a circuit?

Back

When a switch is open, the circuit is incomplete, and electricity cannot flow, so devices like light bulbs will not work.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the components are connected in a single path, so the same current flows through all components.

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 electricity to flow.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is a light bulb in a circuit?

Back

A light bulb is a device that converts electrical energy into light energy when electricity flows through it.

Front

What materials can be used to complete a circuit?

Back

Materials like metal (e.g., aluminum foil, copper wire) can be used to complete a circuit because they are good conductors.

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 flow) or closing (allowing flow) the circuit.
