Capacitors in the power supply
How to find the values of capacitors required for Power Supply …
The capacitor is charged over a period of a few milli-seconds and, becomes slightly discharged by the regulators and load current. This is why those capacitors are so large - they have to supply a near constant voltage between re-charge pulses delivered through the bridge rectifier. Here is a good article that explains how to calculate the ...
