(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Determine how long it takes the capacitor to discharge to a value of 3v

C=1.5E-6F

R=1E3ohms

Vi=25v

Vf=3v

2. Relevant equations

T=RC

v=Vi*e^(t/T)

3. The attempt at a solution

T=1000*1.5E-6

T=1.5E-3s

Vf(3v) is 12% of the initial 25v

Im having trouble solving for time with this equation v=Vi*e^(t/T)

many thanks in advance
