Under assumption that input voltage Vi has the amplitude of 1V calculate input current I to the circuit presented in Figure 1 assuming R=1k? and C=10 µF. Using equations below obtain an amplitude ratio of the voltages Vi /V0 and a phase shift ? between them at 50 Hz and 5MHz. What theoretically you can conclude about RC circuit? $\frac{V_o}{V_i} = \frac{1}{R + \frac{1}{j\omega C}} = \frac{1}{1 + j\omega RC} = \frac{1}{\sqrt{1 + (\omega RC)^2}} \angle -tan^{-1}(\omega RC)$ $V_o \text{ Laggs } V_i \text{ by } \theta = tan^{-1}(\omega RC)$ Under assumption that input voltage Vi has the amplitude of 1V calculate input current I to the circuit presented in Figure 2 assuming R=1k? and C=10 µF.

1. A salient-pole generator is rated at 20 MVA, 24 kV and has a direct-axis subtransient reactance of 0.25 pu. The negative- and zero-sequence reactances are 0.35 and 0.10 pu. The generator neutral is solidly grounded. With the generator operating unloaded at rated voltage with $E_{an} = 1.0\angle0^\circ$ pu, a single-line-ground fault occurs at the machine terminals on phase a. Determine the subtransient current in the generator and the voltages to ground for subtransient conditions due to the fault. (2064 A; $V_a = 0\angle0^\circ$ pu, $V_b = 1.013\angle-102.3^\circ$ pu, $V_c = 1.013\angle102.3^\circ$ pu)
