## Homework Statement

A capacitor with initial charge q0 is discharged through a resistor.

(a) In terms of the time constant τ, how long is required for the capacitor to lose the first one-third of its charge? answer x tau

(b) How long is required for the capacitor to lose the first two-thirds of its charge?

answer x tau

## Homework Equations

i = -(q

_{0}/RC)e

^{(-t/RC)}

## The Attempt at a Solution

I tried solving for time t and got -RC*ln(q/q

_{0})= t

I'm lost i don't know what to do
