1. For the circuit of Figure 1, VT = 100 V, R = 5000 Ω and C = 400 μF; switch S is closed at t = 0.
a) Determine the instantaneous power absorbed by the capacitance.
b) Obtain an expression for the instantaneous power dissipated in the resistance.
c) Determine the voltage across the capacitor at time t = 1.39 s.
A 75-Ω resistance is connected in parallel with a 10-μF capacitance. Determine an equivalent series RC circuit such that the two circuits have the same impedance at an angular frequency of 1000 rad/s.
If a voltage source is connected to the parallel RC circuit as shown in Figure 2, determine the maximum energy absorbed by the capacitor.
