Hello friends.
I have a very basic question about capacitors which might sound very idiotic but I really must understand it.
A capacitor basically opposes changes in voltage. But what happens when we have a sinusoidal waveform between 90° and 180°
Consider the following circuit:
Between 0° and 90° the current flows clockwise and the capacitor charges and at the same time opposes the change with the maximum opposition occurring at 90°. Between 90° and 180° the current still flows clockwise but the voltage starts to descend in amplitude. This means that the capacitor should oppose the descending voltage and does so by discharging counter clockwise and herein lies my problem - by discharging counter clockwise it seems to actually exasperates the descend in amplitude instead of resisting it!!!
What am I missing here?
Thanks
