Question 635: 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
$$P = {{{V^2}} \over R}$$
$${{{P_1}} \over {{P_2}}} = {{{R_2}} \over {{R_1}}}$$
$$ \Rightarrow {{{P_1}} \over {{P_2}}} = {{200} \over {100}} = {2 \over 1}$$
