Homework Statement
I need to rearrange the equation for exponential growth of voltage across capacitor during charging.
Homework Equations
Equation is Vc=Vs(1-e^-t/CR) I need to find out how long it takes for Vc=26v with Vs=40v thus rearranging the equation making t the subject.
The Attempt at a Solution
Ive forgotten what to do with Logs and therefore am stuck on this part.
LnVc=LnVs-t/CR
Im not sure if its correct but sincerely appreciate any help and advice I've calculated the time in a circuit and found t=10.4977 so need to prove it mathematically!
Thank You
