The components' values are R-47,C-0.016 F, and L 24 H series AC circuit contains a voltage source, a resistor, a capacitor, and an inductor The voltage source 17% Part (a) Calculate the capacitive reactance of the circuit, in ohms. Grade Deduc Potent tano t cotan a acos0 ata acotan sin0 cosbo tanbO cotanho Submi Degrees Radians Subenit Hint Hints:--dehction per hat Hints remaining ii 17% Part (b) Find the inductive reactance ofthe circuit, in ohms. 17% Part (d) Find the maximum current in the circuit, in amperes. Feedback:-deduction per feedback & 17% Part (c) Calculate the circuts impedance, tn ohms 17% Part (e) Calculate the rms current in the circuit, in amperes 17% Part () Find the average power delivered to the circuit, a watts.Explanation / Answer
(A) Xc = 1 / w C = 1 / (85 x 0.016)
Xc = 0.74 ohm
(B) XL = wL = 85 x 2.4 = 204 ohm
(C) Z = sqrt(R^2 + (XL - XC)^2) = 208.6 ohm
(D) Imax = Vmax / Z = 150 / 208.6 = 0.719 A
(E) Irms = Imax / sqrt(2) = 0.508 A
(f) P_avg = Irms^2 R = 12.15 Watt
