FN.Q3 - The circuit connected to an AC voltage source; $V_s = 330.Sin(314t)$ Volt. Inductance of the coil: $L = 135 mH$ and of the resistance: $R_L = 7 \Omega$, and the load resistance $R_A = 52 \Omega$ are given. Find the values of impedance Z of the circuit, current $i_s$, voltage of coil $V_{coil}$, voltage of resistance $V_{RA}$ and $Cos\varphi$ of the circuit. $(\pi = 3.14, V_{RMS} = V_M / \sqrt{2})$
