I need the answer as soon as possible

Extracted text: 30 v(t)= 100 sin(10r) at t< 0="" ac="" v(t)="200" sin(101)="" at="" t="">0 A coil has been connected to an AC source for a long time and at t-0 the voltage source has changed from v.(t)= 100 sin(10/) to v.(t)= 200 sin(10r). If the reactance and resistance of the coil is 40 and 30 respectively, then, the circuit current i(t) is Rt i(t) = is.s.(t) + [200 + is.s.(0*)]e I - %3D ww Rt i(t) = is.s.(t) - is.s.(0*)e T %3D Rt i(t) = is.s.(t) + [200 - is.s.(0*)]e I Rt i(t) = is.s.(t) + [100 - is.s.(0*)]e %3D
