Discussion Overview

The discussion revolves around finding the voltage at a specific time (t=1) in an electrical circuit involving a capacitor. Participants are exploring the relationship between voltage, current, and capacitance, and are seeking assistance in applying relevant equations and principles.

Discussion Character

  • Technical explanation
  • Mathematical reasoning
  • Homework-related

Main Points Raised

  • One participant states that they know the initial voltage V(t=0) is 20 and the capacitance is 0.1, but they are struggling to find V(t=1) to calculate dV/dt.
  • Another participant asks for any work or relevant equations that have been attempted, indicating a need for clarification on the approach.
  • A third participant suggests that the problem involves a differential equation and prompts the use of Kirchhoff's Voltage Law to determine the solution, while expressing uncertainty about the academic level of the original poster.

Areas of Agreement / Disagreement

Participants are engaged in a collaborative inquiry, with no consensus reached on the specific method to find V(t=1) or the correct application of Kirchhoff's Law. The discussion remains unresolved.

Contextual Notes

There are limitations regarding the assumptions made about the circuit configuration and the specific equations that may apply. The academic level of the participants is also not clearly defined, which may affect the depth of the discussion.

I know that V(t=0) is 20 and time = 1 and capacitance = .1
what I'm having trouble is finding V(t=1) to find dV/dt. Can someone help me?

Any work that you've tried and/or relevant equations you could use?

Yeah relevant equations are

And I'm not asking for the answer. More of if someone can explain to me how to find voltage at time = 1

Okay right now you have a differential equation. Can you follow Kirchoff's Voltage Law to determine what that is going to be? I'm not sure at what level you are academically, so I'm not sure if the derivation would be the correct path to go down...
