Question

What happens to the current supplied by the battery when you add an identical bulb in parallel to the original bulb?

1) The current supplied by the battery decreases
2) The current supplied by the battery increases
3) The current supplied by the battery remains the same
4) Cannot be determined without additional information

Answer 1

When you add an identical bulb in parallel to the original bulb, the current supplied by the battery increases.

Step-by-step explanation:

When you add an identical bulb in parallel to the original bulb, the total resistance of the circuit decreases. According to Ohm's Law, V=IR, if the resistance decreases and the voltage remains the same, the current will increase. Therefore, the current supplied by the battery increases when you add an identical bulb in parallel to the original bulb.
