Hello i have a question about a RC circuit. Can i represent with Laplace Transform the discharging of RC curcuit and how i get the transfer funtion to represent the free responce of the system

Here's the question : "For the two port network given, obtain the Z-parameters, ABCD (transmission) parameters and h (hybrid) parameters. What should be the value of load resistance connected at Port-2 for maximum power transfer when a voltage source of 25V is connected at Port-1." (Picture...

Good day! I am currently writing a short report on DC machines and I intended to use the generator onboard the Bombardier/DHC Dash 8 Q400's Auxiliary Power Unit as a focal topic. Upon searching through several documentation (both from Bombardier themselves and some airlines like AirBaltic) I...

I have a problem in my ET212 class that I truly have no idea on where to start, I have the circuit design, but am clueless when it comes to the values that I need to use. I am not asking for answers, mainly just guidance on where I am supposed to start, or the steps i need to do to find my...

Hello. This may be a simple problem, but I'm struggling to obtain the resistance R found in the figure below. First what's throwing my are the two voltage sources. I'm used to seeing these present in op-amps, but the way they intersect is throwing me. I'm not sure how to determine their...

Circuit problem: I have the answers to it, but I need to know the process of how to get there.

Hello, I got a homework exercise about the calculation of the power factor in a RL-circuit and in a RLC-circuit. The question consists of 3 sub questions, I have managed to calculate the first 2 however I am struggling with the third one. For the calculation of the third question, the other 2...

Hello, Trying to solve this and using LT-spice for confirmation I can't verify my solution. Where could be wrong ? Here is my try: Thanks

The question is asking what the resistance of the first resistor is (which has been labelled as 0 ohms on the diagram). I am told 20v drops across the first resistor and i am given the value of the other resistor. Now both of the methods I am sure I've done correctly but I'm getting different...

I need to design a circuit to calculate the product of two 4-bit binary numbers, and then display the decimal result in three HEX displays.I already have the multiplication part, but the hex baffles me since : 1-The inputs are two 4-bit binary numbers. 2-The system can display each input...

Hello, I've been having difficulty dealting with circuit analysis. Here, for example, I'm given the task to find the voltage on Vs. But I fail short half-way through. Also, I don't understand how to deal with negative voltages and/or currents, and would appreciate help! My attempt at solving...
