Two identical bulbs are connected in parallel across the battery shown in Figure Q16.2. There is an open switch next to bulb 2. Initially, bulb 1 is bright (strong current) and bulb 2 is dark (no current). How do the electric currents change when the switch is closed?

(a) The current through the battery is the same but now splits between 1 and 2.

(b) The current in 1 is still bigger than that in 2.

(c) The current in 1 does not change and is the same as in 2.

(d) The current through the battery doubles.

(e) Both c and d are correct.
