Two electric bulbs `A and B` are rated `60 and 100 W`, respectively. If they are connected in parallel to the same source , then

Options

A. both the bulbs draw the same current
B. bulb `A` draws more current than bulb `B`
C. bulb `B` draws more current than bulb `A`
D. currents drawn in the bulbs are in the ratio of their resistances

Answer

C

Explanation

Given `P_(A) = 60 W` , `P_(B) = 100 W`. We know that current flowing through the bulb is `I = P//V`. We also know that as both the bulbs are connected in parallel , potential difference `(V)` across both the bulbs is the same . Thus , `I prop P`. Since the power of bulb `B` is greater than that of bulb `A`, bulb `B` draws more current than bulb `A`.
