A series L R circuit is connected to a voltage source with V t = V 0 sin ω t . After a very large time, current I t behaves as t 0 ≫ L R :

Correct answer

3

Step-by-step solution

When sinusoidal voltage is applied across L R circuit, current is also sinusoidal but it lags by some phase. Current will be in the form of I = I 0 sin ω t - ϕ Graph will be sinusoidal. Here I 0 is the maximum current and ϕ is phase difference between V   &   I
