A 60-W light bulb and a 100-W light bulb are connected in series to a 120 V outlet.Which light bulb has more current in it?
A)the 60-W bulb
B)the 100-W bulb
C)Both have the same current.

Question

Quizplus · Accepted Answer

Both bulbs are connected in series, which means that they have the same current flowing through them. The total current in the circuit is determined by the voltage of the outlet and the total resistance of the circuit. Since the two bulbs are in series, their resistances add up, so the total resistance of the circuit is higher than if there was only one bulb. This means that the current flowing through both bulbs will be lower than if there was only one bulb, but it will be the same for both bulbs. Therefore, both bulbs have the same current flowing through them.
