Question

Ratio of thermal energy released in two resistors R and 3R connected in parallel in an electric circuit is:

G1 Physics · Accepted Answer

For resistors in parallel, the potential difference is the same. Heat produced in time t is H = V²t/R. Therefore H(R)/H(3R) = [V²t/R]/[V²t/(3R)] = 3:1.
