(1) Consider the RC circuit shown in Figure 1. For t<0 the switch is open, and the charge stored on the capacitor is 0. At t-0 the switch is closed, and the voltage source begins charging the capacitor. Let R1-R2-220 Ω , C-0.47 μ F , Vs-5 V. (a) Write the differential equation as an expression for the capacitor voltage fort> 0 (i.e. write the differential equation) and calculate the time constant (b) Calculate the steady-state capacitor voltage R2 R1...
Can you help me do b)? In the circuit below, a) For t < 0, the switch has been open for a long time, find the inductor current? b) For t > 0, the switch is closed at t=0, find the inductor current using Thevenin's equivalent at the terminals a and b? And sketch the current waveform? c) Then find the steady-state, transient, forced and natural components? 22 V 10 v t=0 X 22 §
