Thank you for the replies! I ran with your recommendations, but I'm afraid I'm still unsure of how to proceed. Here's what I was able to do so far: Unfortunately op-amps are the first amplifiers that we've covered. This is the first that I've heard about Ideal voltage amplifiers actually...

Another classmate and a web search show that the answers for this problem are v0 = -12 V, and i0 = 2.4 mA. This was done using KVL around the circuit. I should be able to reach the same answer using KCL but I haven't and I'm not sure why. Is it because the source isn't connected to ground and so...

I'm sorry if I've convoluted this. My questions is this: Given only the circuit and the following prompt, is this solvable? "Find the values for R1 and G (gain) in following circuit (15 points) Hint: start by writing a KCL at bottom node"

I've attached a screen shot of the original circuit and problem as read in the textbook. I assume that the textbook has it this way more as a study in what if or something. Also, I don't know if this was clear, but I already have the numerical answers for each variable: R##_1## = 100...

I've gotten to the point where I've hit a roadblock and am not sure what step to take next. I started by using KCL on the bottom node as suggested by the problem, then used KVL on the left mesh, but I still have ##i_{v_s}## which I'm not sure what to equate it to, so that I can pull it out of...

The first thing that comes to mind is the gate to my parking structure. We bought a programmble controller that broke shortly thereafter. I've toyed with the idea of making one myself off and on. I could buy one, of course, but I find the idea of making one from scratch interesting. A power...

Howdy all. I haven't played around with building any circuits recently and so I'm pondering small projects that can be done for around 50 $US, though I'm willing to spend as much as 100 %US on parts. I have a soldering iron and experience using it and some familiarity with components (as well as...

Oh! Thank you! I was struggling to make the connection. I overlooked that entirely. It makes sense now. Thank you very much!

So I should have continued to manipulate the equation algebraically before integrating? Replacing ##I## with something else?

That was part a of this question: Just after the circuit is completed, what is the rate at which electrical energy is being dissipated in the resistor? The answer was 855 mW. Using the trick provided by Delta##^2## I solved for ##V_c = 37.3~V## then took ##I = \frac {dq} {dt} \rightarrow I dt...

Homework Statement 1. A 2.01 uFcapacitor that is initially uncharged is connected in series with a 6.51 kΩ resistor and an emf source with 74.6 V and negligible internal resistance. The circuit is completed at t = 0. b) At what value of t is the rate at which electrical energy is being...

Ok, thank you! mJ/s seemed weired but I guess it felt more fitting as a rate than simply W, which I still don't immediately associate with rate.

Got it. Thanks!

Alright. I'll try to keep that in mind then.
