In the circuit as shown in the figure, the heat produced by 6 ohm resistance due to current flowing in it is 60 calorie per second. The heat generated across 3 ohm resistance per second will be
Text Solution
Verified by ExpertsThe correct answer is:
D
Resistance of upper branch 
Resistance of lower branch 
Hence 
∴ ∴ Heat generated across 3 Ω Ω = 120 cal/sec
