 
 <prompt> Wetin need handle 100% voltage reversal? Given di previous question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: For maximum life, capacitors usually need to fit handle the maximum amount of reversal wey system go experience. An AC circuit go experience 100% voltage reversal, while under-damped DC circuits go experience less than 100%. Reversal dey create excess electric fields for the dielectric, dey cause excess heating of both the dielectric and the conductors, and fit dramatically shorten the life expectancy of the capacitor. Reversal ratings fit affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections wey dem go use.
