AI Thread Summary
The discussion centers on calculating the voltage V(t=1) in a circuit where V(t=0) is known to be 20 volts and the capacitance is 0.1. The original poster is struggling to determine V(t=1) in order to find the rate of change of voltage, dV/dt. Participants suggest using Kirchhoff's Voltage Law to derive the necessary equations. There is an emphasis on understanding the differential equation involved in the circuit analysis. Clarification on the academic level of the participants is also mentioned to tailor the explanation appropriately.

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...
