Discussion Overview

The discussion revolves around a circuit problem involving an independent current source and the determination of the voltage drop across it. Participants explore the application of Kirchhoff's laws and share their calculations related to the circuit's behavior.

Discussion Character

  • Technical explanation, Mathematical reasoning, Homework-related

Main Points Raised

  • One participant expresses confusion regarding the voltage drop of an independent current source, noting that it seems to depend on the same node as the current source while being parallel to a power source.
  • Another participant suggests applying Kirchhoff's voltage law to analyze the circuit.
  • A participant reports calculating a voltage of 85 volts and seeks confirmation of this result.
  • A later reply confirms the 85 volts calculation and provides a detailed breakdown of the equation used, including the application of Kirchhoff's Current Law (KCL) to find the current.

Areas of Agreement / Disagreement

Participants appear to agree on the calculated voltage drop of 85 volts, with at least two confirming the same result. However, the initial confusion regarding the behavior of the current source remains unaddressed.

Contextual Notes

The discussion does not clarify the assumptions made regarding the circuit configuration or the definitions of the components involved, which may affect the interpretation of the results.

Who May Find This Useful

Individuals studying circuit analysis, particularly those interested in the application of Kirchhoff's laws and the behavior of current sources in circuits.

Hello all. I am doing a basic circuit problem but ran got into a bind. I have a independent current source and need help finding the voltage drop of that current source. I did some research and found that current sources will always carry the same voltage as the power source no matter what's in between. However this independent current source as a voltage dependent on the same node as the current source, but the power source is parallel to the current source. Thanks in advance!

Im really hoping everyone can access this. I tried a million different file types and it constantly said I exceeded the file size.

Hi csmith23,

I am also learning circuits right now and so I could be wrong, but have you tried applying Kirchoffs' voltage law around the first loop?
 
I did that shortly after posting this. And I got 85 volts. Can anyone confirm if that is correct?
 
Yep! I got the same answer.

$$V_A=V_x+4V_y+10i=4+4(5)+10(6)=85V$$
I got $i=6$ by applying KCL around the first node.
