Finding Thevenin Equivalent: 6 Ohm Resistor

Click For Summary

Discussion Overview

The discussion revolves around finding the Thevenin equivalent of a circuit involving a 6 ohm resistor. Participants are exploring methods to determine the equivalent resistance and voltage, with a focus on circuit analysis techniques.

Discussion Character

  • Technical explanation
  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant expresses uncertainty about how to begin finding the Thevenin equivalent and questions whether to divide the circuit into parts.
  • Another participant suggests that since there are no dependent sources, one can deactivate all voltage and current sources to find the Thevenin equivalent resistance.
  • A participant mentions calculating the equivalent resistance (Req) from one side of the circuit, arriving at a value of 1 ohm, and questions the process for finding Req and the open-circuit voltage (Voc).
  • Another participant agrees with the need to remove the 6 ohm resistor to create an open circuit for finding Voc and discusses combining the resistances from both sides of the circuit in parallel.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the approach to finding the Thevenin equivalent, with differing opinions on the steps to take and the calculations involved.

Contextual Notes

There are unresolved aspects regarding the calculations of equivalent resistance and voltage, as well as the specific configuration of the circuit, which may affect the analysis.

I have to find the thevenin equivalent of the following circuit in order to find the current and potential difference across the 6 ohm resistor. I can not get to know that where should I start. Should I divide the circuit into 2 parts or what?

Update: No you don't have to do that. Since there are no dependent sources, you can kill all voltage and current sources to find the Thevenin equivalent resistance. Then either find the open-circuit Thevenin voltage or the short circuit current.

I have learned to find the thevenin equivalent of one port circuits only. If I find Req from right it comes out to be 1 ohm. Where should I start to find the Req? and to find voc Ill have to remove the 6ohm resistor right?
 
Ok I didn't check your 1 ohm calculation. But if you find the Req for right and left parts of the circuit, then the total Req is the equivalent resistance in parallel.

As for the Vth, yes you have to remove it to make an open circuit.
