Two electric bulbs whose resistances are in the ratio of 1 : 2 are connected in parallel to a constant voltage source. The powers dissipated in them have the ratio

A

1 : 2

B

1 : 1

C

2 : 1

D

1 : 4

Answer

2 : 1

Explanation

Solution

We know that P1P2=R2R1=21\frac{P_{1}}{P_{2}} = \frac{R_{2}}{R_{1}} = \frac{2}{1}
