Discussion Overview

The discussion revolves around discrepancies between calculated and simulated values in a circuit using Multisim. Participants are examining the output voltage (Vout) and seeking assistance to reconcile the differences between their calculations and the simulation results.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant reports a calculated Vout of -2.1V, while the Multisim simulation yields a positive value, expressing confusion over this discrepancy.
  • The same participant mentions that the input voltage (Vin) is set to 0V, as instructed by their lecturer, and seeks help to achieve a matching Vout with their calculations.
  • Another participant attempts to download a shared file related to the circuit but encounters issues.
  • A later reply indicates that the file is now accessible through a different hosting link.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the cause of the discrepancy between calculated and simulated values, and the discussion remains unresolved regarding the specific reasons for the differences.

Contextual Notes

Limitations include potential missing assumptions in the circuit design, dependence on specific definitions of circuit parameters, and unresolved steps in the mathematical calculations leading to the reported values.

This is the value after i calculate ,but use multisim to simulate this circuit,i get a answer different completely with the calculate answer.Example the Vout,also is most importent value,the calculate answer is -2.1V,but the answer of simulation is possitive value!y will like this?It i use the wrong way?The value of Vin the lacturer want us input 0V,so i connect to ground.I have attached the msm file of multisim and the graph with answer i calculate,wish got ppl can help me...most important is can let the Vout same with value of calculate,equal -2.1V.thank you very much...
