Hi!

I hope you can help, cause I'm kind of stuck here.

I have an AC circuit with a voltage, where the amplitude V_0 is 23V, the period T is 0.6 ms. The curve is so that the first maximum peak is at 0.2 ms. I have found that the function must be

V(t)=23 * cos(2*pi*(1/0.6)*t - 0.2*2*pi*(1/0.6))

The corresponding current has an amplitude of I_0=20 mA, the period T is still 0.6 ms). The curve has the first minimum peak at 0.6 ms. I have found that the function must be

U(t)=20 * cos(2*pi*(1/0.6)*t-pi)

Now my job is to determine the complex impedance in real/imaginary form and in polar form. Heeelp!

I also have to draw a phasor diagram at time t = 0. Heeelp!

I really hope you can help, cause I'm really stuck!
