Step 1
The impedance of the resistor is $Z_R = R = 75\Omega$. The impedance of the inductor is $Z_L = j\omega L = j(1500)(0.12) = j180\Omega$. The impedance of the capacitor is $Z_C = \frac{1}{j\omega C} = \frac{1}{j(1500)(50 \times 10^{-6})} = \frac{1}{j0.075} = Show more…

Refer to the following circuit. It is assumed that the circuit is operating in steady-state. a. Determine the total impedance of the circuit, Zeq; b. Determine the phasor form of the source voltage Vs, the current Iss, the voltage across the inductor VL, the voltage across the capacitor VC, the voltage across the resistor VR. c. Verify KVL, VS = VL + VC + VR, by drawing phasor diagram and doing vector addition. d. Specify phase relationship of VR, VL and VC with respect to VS.

31.15. (a) For the $R-L$ circuit of Exercise $31.14,$ graph $v, v_{R},$ and $v_{L}$ versus $t$ for $t=0$ to $t=50.0 \mathrm{ms}$ . The current is given by $i=I \cos \omega t,$ so $v=V \cos (\omega t+\phi) \cdot(\mathrm{b})$ What are $v, v_{R},$ and $v_{L}$ at $t=20.0 \mathrm{ms} ?$ Compare $v_{R}+v_{L}$ to $v$ at this instant. $(\mathrm{c})$ Repeat part $(\mathrm{b})$ for $t=40.0 \mathrm{ms}$
