Sylvia tested a material in the science lab. She put it between a wire and a battery in a closed circuit. What evidence might have led her to decide the material is an insulator?

Question

A
The battery did not die.

B
She did not create a short circuit.

C
The wire got hot.

D
The light bulb was off.

Answer 1

The correct evidence that might have led Sylvia to decide the material is an insulator is:

D. The light bulb was off.

If the light bulb was off, it indicates that there was no flow of electric current through the circuit, which suggests that the material acted as an insulator and prevented the electrical current from passing through.
