Problem 2. Assume the given circuit is in steady state before the switch closes at t = 0. Determine: The time constant for this circuit. The time-domain expression for the inductor current for t > 0. The time needed after the switch closes for the current to decay to 0.1 amps

For the circuit in Figure 3 the switch is in the left position for several minutes: (a) Find the Initlal voltage, V, on the capacitor just before the switch is flipped (b) Find an expression v(t) that describes the voltage across the 20 N resistor after the switch has been Figure 3 U 09 flipped to the right NOTE: Remember what we said in class: use a Circuit-Specific Equation to get a value you know. Then solve for whatever else the problem asks for +50 µF 380 0 20 2

Hello. This is practice for my own study (nothing is for a grade, just practice). I am more interested in a clear & organized, efficient process/methods. Please use "jw" as that is what I'm more accustomed to seeing. Thank you in advance.

Conduct transient analysis on the following RL circuit. The pushbutton switch S1 is normally open. Consider this scenario: (1) Begin with switch S1 open, (2) close switch S1 long enough till the voltage across the inductor is almost zero, and then (3) open switch S1 for a long time beginning at time t = 0. We would like to demonstrate how an inductor can produce a high- voltage pulse across a load resistance R3 that is considerably higher than the circuit's power supply V1, a 1.5-volt supply. Consider R1 = 10 22, R2 = 10022, R3 = 47022, L1 = 33mH, Determine the voltage v across R3 after the switch S1 has been closed for a long time. Determine the equation that describes v (t) after the switch opens at time t = 0. Determine the magnitude of the peak value of v (t). How many times larger is this value compared to the original voltage source V1 = 1.5V? State the value of the circuit time constant T with the switch open. Plot v (t) over the time range ● ● - T ≤t ≤5T R1 www 102 V1 1.5 V.…
