Two 2Omega resistances are connected in parallel in the 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 resistor 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 |

Answer» `(1)/(4)W` In a circuit Y, both resistance are in series. Therefore, `V_(B)+V_(B)'=V or V_(B)=V//2` In a circuit Y, power supplied to `B=((V//2)^(2))/(2)=(V^(2))/(8)=(W)/(4)` |
