Problem 4. A 10 mH inductor has a sudden current change from 200 mA to 100 mA in 1 ms. Find the induced voltage. Problem 5. A induced voltage across a 10 mH inductor is v(t) 120 cos (377t) V. Find (a) the expression for the inductor current and (b) the expression for the power. The current in a 25 mH inductor is given by the expressions: i(t) 0 i(t) 10 (1-e) mA Find the voltage across the inductor and...
A current i(t) = 220 sin (20pi t) mA is applied to a capacitor of C = 20000/pi mu F, as shown in the figure below: a) Knowing that i(t) = C dv/dt, integrate both sides of the equation to determine the voltage v(t). You may assume that the initial voltage is v(0) = 0.55 Volts. b) Plot one cycle of the voltage v(f) found in part a) and clearly indicate the amplitude, frequency, and period on the plot. Also,...

I did this normallt but I need to use laplace tranforms. The differential equation for a single closed RL-circuit is, by Kirchoffs Second Law, di where i() is the current in the circuit at time t, L is the inductance, R is the resistance, and E(t) is the impressed voltage. In this lab you will investigate the current under voltages that are nonzero for only a brief period of time. Assuming the values L R 1, solve the LR- circuit...
I can find iL(0+) and vC(0+), but I cannot find tm and Vcm. The final answer is given for Vcm=-4.718 V and tm=1.7018 ms In the circuit shown below, the switch was open for a very long time and closes at t = 0. Calculate: 1. The initial value of inductor current, IL(0*), 2. The initial value of capacitor voltage, vc(0*), 3. The minimum value of the capacitor voltage, Vcm, 4. The time, tm, when the minimum in p.3 occurs....
