why does the capacitor charge to the peak of the Ac and not any other point ?

why does the capacitor charge to the peak of the Ac and not any other point ?

and we know that the time of charge equals the time of the discharging why this is not the case here ?

When you pour water into a bucket..........does the water level rise? It has too.....doesn't it.

The reason the cap charges to peak.....it because it has too.....it has no where else to go......like water in a bucket.

BR-549 nice explanation that was easy to understand ^^

so basically the capacitor has already a higher voltage than the source so it starts to discharge , hopefully this is what u mean :)

@dl324 has it right. For a bridge rectifier, R is very small and we're usually talking about 50 or 60 Hz (low and slow). That means there is plenty of time to move several time constants along the charge curve. But that's just one application out of many.
