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
i = -(q0/RC)e(-t/RC)
The Attempt at a Solution
I tried solving for time t and got -RC*ln(q/q0)= t
I'm lost i don't know what to do
