Two 2 Ω Ω resistances are connected in parallel in circuit X and in series in circuit Y. The batteries in the two circuits are identical and have zero internal resistance. Assume that the energy transferred to resistance A in circuit X within a certain time is W. The energy transferred to resistor B in circuit Y in the same time will be
Text Solution
Verified by ExpertsA
In circuit X, both the resistances are in parallel. Therefore V is the same and, Power (energy transferred in unit time) is 
In circuit Y, both resistance are in series. Therefore
or 
In circuit Y, power supplied to
