Two resistors of resistance, 100 Ω100\text{ }\Omega and 200 Ω200\text{ }\Omega are connected in parallel in an electrical circuit. The ratio of the thermal energy developed in 100 Ω100\text{ }\Omega to that in 200 Ω200\text{ }\Omega in a given time is

A

1:21:2

B

2:12:1

C

1:41:4

D

4:14:1

Step-by-Step Solution

For parallel combination, power P=V2RP = \frac{V^2}{R}. Therefore, P1P2=R2R1=200100=21\frac{P_1}{P_2} = \frac{R_2}{R_1} = \frac{200}{100} = \frac{2}{1}.
