How to find the current and voltage in a circuit with current sources?

Click For Summary

Discussion Overview

The discussion revolves around analyzing a circuit containing two parallel resistors and two current sources (one dependent and one independent). Participants are attempting to determine the current, voltage, and power associated with these components, particularly focusing on the current i0 and the implications of the current sources on the circuit behavior.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about how to find the current i0 due to the presence of the current sources and mentions the formula I=V/R but lacks the voltage value.
  • Another participant notes that the voltage across the 2 ohm resistor is the same as that across the 8 ohm resistor because they are in parallel.
  • A different participant suggests using nodal analysis to find the voltage v_o, indicating that once this voltage is known, the current i_o can be easily determined, and that the power calculations should follow from this analysis.

Areas of Agreement / Disagreement

Participants present various approaches to solving the problem, but there is no consensus on a specific method or solution. The discussion remains unresolved as participants explore different strategies.

Contextual Notes

There are limitations in the information provided, such as missing values for voltage and the specific configuration of the circuit elements, which may affect the analysis. The discussion also relies on assumptions about the circuit's behavior based on the arrangement of components.

Summary: Facing a circuit with 2 parallel resistors and 2 current sources (1 dependent, 1 independent). Trying to find the current, voltage, power delivered by the independent current source and power delivered by the dependent current source.

I'm trying to start by finding the current i0 but I'm not sure how to because of the current sources and how it affect it. also I know that to find the current I should use I=V/R , but I only have R=2 and without V (Not really sure!).

Welcome to PF.

I moved your question to a homework thread. Next time, post it in the homework section, and fill out the template of required information the forum will provide.

Whatever the voltage is across the 2 ohm resistor is also the voltage across the 8 ohm, from the fact that it's a parallel arrangement.
 
The circuit has only one essential node, so conciser using nodal analysis to find the voltage ##v_o##. With that, the current ##i_o## is obvious. The remainder of the questions to be answered (power delivered (or absorbed!)) should be evident after the node voltage is determined. If not, be sure to ask questions about that. We're here to help :smile:
