Question

Two resistors R and 2 R are connected in series in an electric circuit. The thermal energies developed in R and 2 R are in the ratio, 1 : 2, 2 : 1, 1 : 4, 4 : 1

MARKS App · Accepted Answer

Thermal energy or heat developed is given by, H = i 2 R t In series combination, the current flowing through all the elements is the same, so H 1 H 2 = R 1 R 2 H 1 H 2 = R 2 R H 1 H 2 = 1 2
