6.2 The voltage at the terminals of the 0.6 μF capacitor shown in the figure is 0 for t < 0 and 40e-15,000 sin 30,000 V for t≥ 0. Find (a) i(0); (b) the power delivered to the capacitor at t = π/80 ms; and (c) the energy stored in the capacitor at t = π/80 ms.

The voltage pulse applied to the 100 mH inductor shown is 0 for t<0. and is given by the expression v(t)=20te−10t V for t>0. Also assume i=0 for t≤0. Sketch the voltage as a function of time.

The current flowing through a 10-μF capacitor having terminals labeled a and b is i ab =0.3 exp( −2000t ) Afor t≥0 Given that v ab ( 0 )=0, find an expression for v ab (t) for t≥0. Then,find the energy stored in the capacitor for t=∞..

All capacitors were initially discharged. at t = 0, S1 is placed at position 1 and S2 is closed. During this phase, it has been determined that Eth and Rth seen by the equivalent capacitor are, respectively, 20 V and 6.0 kΩ. The time constant is 29 ms.  At t = 15 ms, S1 is placed at position 2 and S2 is kept closed. Calculate the equivalent capacitor voltage vT at t = 15 ms. Enter your answer in V rounded to 2 decimal places. At t = 25 ms, S1 is kept at position 2 and S2 is opened. Data: R1 = 5 kΩ, R2 = 3 kΩ, R4 = 2 kΩ, R5 = 20 kΩ, R6 = 12.0 kΩ;
