I would like to have some help with this problem:
U = 93 [V]
f = 600 [Hz]
L = 0,24 [H]
C = 0,16 [μF]
R = 950 [Ω]
This is the RCL circuit which I need to find the impedance Z\$Z\$ in and \$ \cos(\alpha) \$\$\cos(\alpha)\$
The first two questions that I had was to find the inductive reactance, XL, and the capacitive reactance, XC. I figured them out and I got XL = 905 ohm and XC = 1658 ohm.
I thought that I would use this formula:
$$\mathrm{impedance} \, Z = \sqrt{R^2+(X_L-X_C)^2}$$
But I can't get it right. I would also like to know if \$ cos(\alpha) \$is\$\cos(\alpha)\$ is solved through \$ \cos(\alpha) = \frac{R}{Z} \$\$\cos(\alpha) = \frac{R}{Z}\$
