Question
A capacitor is discharged through a 100 resistor.The discharge current decreases to 23% of its initial value in 2.2ms. What is the value of the capacitor?Answer = _____________ µF
I know Gort solved a similar one just like this but I justcan't seem to get the right answers with the numbers I have. Ibelieve I know the formula.. Any help is appreciated.

Explanation / Answer
v = v0e^(–t/RC) 0.23 = e^(-(0.0022)/100C) Solve for C C = .00001497 F or 14.97 uF
