While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to change the battery to a higher voltage, but she kept the same light bulb. What will happen to the current?

C It will fluctuate.It will fluctuate.
D It will remain the same.It will remain the same.

Answer 1

The correct response is:

A It will increase.

Increasing the voltage in a circuit while keeping the same resistance (in this case, the light bulb) will increase the current according to Ohm's Law, which states \( I = \frac{V}{R} \) (where \( I \) is the current, \( V \) is the voltage, and \( R \) is the resistance). If the voltage is increased and the resistance remains constant, the current will increase.
