For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system may experience. An AC circuit experiences 100% voltage reversal, while underdamped DC circuits experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can …

Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts.
