If we don't have an electric lamp while making an electric circuit with an electric cell is there any other Class 8

If we don't have an electric lamp while making an electric circuit with an electric cell, is there any other way through which we can find out if current is flowing in the circuit? Class 8

Answer:

Yes, we can use other things to check if current is flowing:

1. Use a buzzer: It makes a sound when current flows.
2. Use a small motor: If it spins, current is flowing.
3. Touch wires to steel wool or thin wire: It may heat up or glow slightly.
4. Use a tester: It shows the flow of current directly.
