A doll's house has a lamp in each of three rooms. The three lamps are connected in parallel with each other to one battery. The lamp in the kitchen breaks, but the other two lamps stay lit.
Which statement explains why the other two lamps stay lit?
The broken lamp no longer uses up current, leaving more for the others
Charge still has a complete path through each of the other lamps
The total resistance of the circuit falls, so the battery's current rises
The battery's potential difference is now shared between fewer lamps
