With $V=V_{o} e^{-t / R C}$, it mathematically takes an infinite time for a capacitor in an $R C$ circuit to discharge. Practically, how many time constants does it take for a capacitor to discharge to less than $1 \%$ of its initial voltage?
Added by Blanca B.
Step 1
We want to find the time it takes for the capacitor to discharge to less than 1% of its initial voltage. In other words, we want to find the time $t$ such that $V(t) < 0.01 V_0$. Show more…
