Electrical engineering hw/Resistive Circuits

Click For Summary

Discussion Overview

The discussion revolves around two homework problems related to resistive circuits in electrical engineering. Participants seek assistance in understanding and solving these problems, with a focus on circuit analysis techniques and the application of Laplace transforms.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant expresses difficulty with two specific homework problems and requests insight after spending considerable time on them.
  • Another participant finds the problem frustrating and seeks help.
  • There is a question regarding whether the source in the circuit is a voltage or current source, with one participant suspecting it to be a current source.
  • Another participant asserts that the source voltage is current and indicates they can solve the second problem independently but finds the first problem challenging.
  • A suggestion is made to sum currents at the input node and to approach the problem in the time domain before transforming to the frequency domain for analysis.

Areas of Agreement / Disagreement

Participants express varying levels of confidence and understanding regarding the problems, with some uncertainty about the nature of the source and differing approaches to solving the problems. No consensus is reached on the best method to tackle the first problem.

Contextual Notes

Participants have not fully clarified the assumptions regarding the circuit elements or the specific details of the problems, which may affect their approaches. The discussion lacks resolution on the mathematical steps involved in solving the problems.

Homework Statement



Im having trouble figuring out these two problems from my home work I've been working on them for 3 hours can anyone give me some insight?

Homework Equations



If the second problem is unclear, F(s) is (3s+4) divided by s(s+2).

Attached is the home work

Please help this problem is extremely frustrating
 
Is the source a voltage or current? I suspect current ...
 
source voltage is current, I can figure out the second problem by myself its just the first one is tricky and I am a bit rusty.
 
Sum currents at the input node. What do you get? Do it in the time domain first if you're not comfortable with transformed impedances.

Then transform each term and solve for V(s), then inverse-transform for v(t). The i(t) and I(s) are obvious ...
