What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow, consisting of a power source, conductors, and a load (like a lightbulb).

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow and power devices like lightbulbs.

Front

What is an open circuit?

Back

An open circuit is a broken loop where electricity cannot flow, preventing devices from working.

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 wood.

What happens when a switch is open?

Back

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

Front

What happens when a switch is closed?

Back

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

Front

What is the role of a lightbulb in a circuit?

Back

A lightbulb converts electrical energy into light energy when electricity flows through it.

Front

What is a series circuit?

Back

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