Two resistors R a
Two resistors are connected in series. In series, the current flows through both the resistors is same.
Energy is given by the formula
I is the current
R is the resistance
T is the time period
Energy developed in the resistor R is
Energy developed in the resistor 2R is
The ratio of energy developed in R and 2R is =
When two resistors R and 2R are connected in series then the ratio of thermal energy developed is 1:2.
Conclusion : Two resistors R and 2R are connected in series, the thermal energy developed in R and 2R are in the ratio 1:2 respectively. So option A is correct.
