Answer #1

A 48-?F capacitor is connected in series with a 32-kΩ resistor
and a 6.0-V DC source. (a) If the capacitor is initially uncharged,
how long will it take the capacitor to charge to within 0.50% of
maximum? (b) If the capacitor is replaced with an 96-mH inductor
and the inductor has no current flowing through it initially, how
long will it take the current through the inductor to be within
0.50% of maximum?
