Question

35. The illustrated circuit contains a battery, a 75 watt bulb, and a 25 watt bulb. (The bulbs consume the specified power when connected to a 100 V battery.)

Which one of the following statements is CORRECT?

a) The resistances of the 25 and 75 watt bulbs are the same.

b) The 75 watt bulb has larger resistance than the 25 watt bulb.

c) The 75 watt bulb has smaller resistance than the 25 watt bulb.

I THOUGHT THE ANSWER WAS B SINCE THE RESISTOR OF THE 75W BULB WAS LARGER BUT THAT WAS INCORRECT. PLEASE PROVIDE ANSWER AS WELL AS AN EXPLANATION TO HELP ME UNDERSTAND THIS! LIFESAVER RATING!
