Capacitor Basics: How do Capacitors Work?
As capacitors store energy, it is common practice to put a capacitor as close to a load (something that consumes power) so that if there is a voltage dip on the line, the capacitor can provide short bursts of current to resist that voltage dip.
power supply
The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output. The white and black bars on the capacitor symbol show that it is a "polar " capacitor - it only works with + and - on the selected ends.
