PhysicsMedium94×since 2002Q5948A series L-R circuit is connected to a battery of emf V. If the circuit is switched on at t = 0, then the time at which the energy stored in the inductor reaches (1n)\left( {{1 \over n}} \right)(n1) times of its maximum value, is :ALRln(nn+1){L \over R}\ln \left( {{{\sqrt n } \over {\sqrt n + 1}}} \right)RLln(n+1n)BLRln(nn−1){L \over R}\ln \left( {{{\sqrt n } \over {\sqrt n - 1}}} \right)RLln(n−1n)CLRln(n+1n−1){L \over R}\ln \left( {{{\sqrt n + 1} \over {\sqrt n - 1}}} \right)RLln(n−1n+1)DLRln(n−1n){L \over R}\ln \left( {{{\sqrt n - 1} \over {\sqrt n }}} \right)RLln(nn−1)Check answerSkip
