Simple Circuits

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows electric current to flow. It must have no breaks or gaps.

Front

What is the role of a battery in a circuit?

Back

A battery supplies energy to the circuit, providing the necessary voltage for the current to flow.

Front

What happens if a circuit is open?

Back

If a circuit is open, the flow of electric current stops, and devices like light bulbs will not work.

Front

What is the symbol for a battery in circuit diagrams?

Back

The symbol for a battery is two parallel lines, one longer (positive) and one shorter (negative).

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 current flows through one component to get to the next.

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 the current to flow.

Front

What is the function 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 electric current to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

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

Front

What is the purpose of wires in a circuit?

Back

Wires connect different components in a circuit, allowing the flow of electric current between them.
