v(1)- 200 sin(10/) at DO
A coil has been connected to an AC source for a long time and at t-0 the voltage source
has changed from v(0= 100 sin(100) to v(t)3 200 sin(10/). If the reactance and
resistance of the coil is 40 and 30 respectively, then, the circuit current it) is
Rt
i(t) = is.s.(t) + [200 - is.s.(0*)]e T
Rt
i(t) = is.s.(t) + [200 + is.s.(0*)]e
