Finding voltage across current source

Click For Summary

Discussion Overview

The discussion revolves around finding the voltage across a current source in a circuit analysis context. Participants are exploring various methods such as node voltage analysis and mesh current analysis, while addressing challenges encountered in solving the problem.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses uncertainty about how to begin solving the problem despite familiarity with node voltage and mesh current analysis.
  • Another participant suggests that the voltage across a current source depends on the impedance connected to it and recommends using mesh analysis.
  • A participant mentions encountering multiple unknowns (i1, i2, i3, V1, V2) and feels unable to progress further.
  • One suggestion is made to find a relationship between the currents i1, i2, and i3, indicating a need for simplification in the analysis.
  • Another participant proposes that a nodal analysis approach could also be effective due to the presence of only one node in the circuit.
  • A further suggestion is made to write down observable relations in the circuit to create equations that could help in solving for the unknowns.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to take, with multiple methods being suggested and challenges acknowledged. The discussion remains unresolved regarding the specific steps to solve the problem.

Contextual Notes

Participants indicate potential missing simplifications and the complexity of having multiple unknowns, which may hinder progress in the analysis.

Hi blakshay.

You need to make a start with this, before we can see where you are having trouble in order to help. Section 2 and Section 3 in the template are there for you to fill in.

Hey,
I have no idea what to do...I know all the node voltage analysis, mesh currents and all that stuff but I'm not sure where to start for this one
 
Just as the current across a voltage source depends on the Impedance connected to it, the voltage across a current source depends on impedence connected to it. I would recommend the MESH Analisis. You should get the answer easily.
 
Yeah I tried that but I ended up wit the 3 unknowns i1, i2 and i3 and also V1 and V2...cant really go further
 
Hint: Try to find a relation between i1, i2 and i3. Have a closer look at the circuit!

Show your attempt. If you've ended up with so many unknowns, something went wrong or you're missing some simplification opportunities.

(I might also suggest, if you're interested, that a nodal analysis approach would also work very well indeed, as there's only one node to worry about...)

If you are really new to circuit analysis, then I suggest that for the moment you shelve all that theory, and just write down whatever relations you can see in the circuit. By the time you are done, you should have enough equations and unknowns to be able to solve it.

For starters, where a current of I flows through the 5Ω resistor, then the current through the 10Ω must be ...

Is it:
(a) 2I
(b) I
(c) 5I
(d) ...
