Question 606: Current Electricity

Question

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

Accepted Answer

For parallel combination
$P = {{{V^2}} \over R}$
${{{P_1}} \over {{P_2}}} = {{{R_2}} \over {{R_1}}}$
$ \Rightarrow {{{P_1}} \over {{P_2}}} = {{200} \over {100}} = {2 \over 1}$
