One disadvantage of this type of circuit is that

a) the addition of new light bulbs decreases resistance.
b) as more lights are added to the circuit, the voltage to each decreases.
c) as more lights are added to the circuit, the current to each increases.
d) when the current to one light is turned on, the current to the other lights turns off.
