COMPLETE AND INCOMPLET CIRCUITS SCIENCE 5

Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electric current to flow from a power source, through a conductor, and back to the power source.

Front

What is an incomplete circuit?

Back

An incomplete circuit is an open loop that prevents electric current from flowing, often due to a break in the path.

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electric current to flow and powering any connected devices.

Front

What happens when a switch is open in a circuit?

Back

When a switch is open, it breaks the circuit, stopping the flow of electric current and turning off any connected devices.

Front

What is the role of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when current flows through it.

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 function 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 parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for the current to flow, allowing devices to operate independently.

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 each component one after the other.
