Turning A of the generator spins a magnet and creates an electric current that lights the bulb. Which of the following observations can be used to indicate the strength of the current created by the generator? * A. The brightness of the bulb
B. The size of the magnet
C. The length of the handle
D. The mass of the generator

A. The brightness of the bulb

Explanation:

An electric current through a circuit turns the lights bulb on. the strength of the current created by the generator will be indicated by the brightness of the bulb because in a closed circuit, the bulb is the only object that is representing that, circuit is properly placed and when bulb lights up only when electrical energy is generated.

More electrical energy generated through the generator means the brighter the bulb glow.

Hence, the correct answer is "A. The brightness of the bulb".
