When two lamps are connected in parallel to a battery, the electric resistance that the battery senses is
A)more than the resistance of either lamp.
B)less than the resistance of either lamp.
C)none of the above

Question

Quizplus · Accepted Answer

When two lamps are connected in parallel, the potential difference across each lamp is the same as that of the battery. Due to this, the current through each lamp is independent of the other lamp. Therefore, the resistance of the individual lamps in parallel decreases, resulting in a lower total resistance. Thus, the electric resistance that the battery senses when two lamps are connected in parallel is less than the resistance of either lamp.
