For the circuit shown in figure 33.4, Vmax = 80.0V, omega = 65 Pi rad/s, and L = 70 mH. Calculate the current in the inductor at t = 15.5 ms
Vmax*sin(wt) - LdI/dt = 0
Vmax*sin(wt) = LdI/dt
dI = Vmax / (L) * sin(wt) dt
I = Vmax / (L) * integral sin(wt) dt
I = Vmax / (L) * (-1) * 1/w * cos(wt)
I = -Vmax/(Lw) * cos(wt)
I = -5.5966 * cos(3.16515)
= 5.588
