SOLUTION :
Vs(t) = 30 cos (100 t)
So, omega , w = 100 rad/s
Impedance of inductor, Z
= w * Inductor L1 in Henries
= 100 * 25*10^(-3) Ω
= 2.5 Ω
R1 = 10 Ω
Resistance to current in the circuit , Rc = R1 + Z = 10 + 2.5 = 12.5 Ω
Current, I(t)
= 30 cos(100 t) / 12.5
= 2.4 cos(100t) Amperers (ANSWER)
Maximum current at t = 0 :
= 2.4 A (ANSWER)
