how does the filter capacitor work in a rectifier circuit?
We commonly call these capacitors "reservoir" capacitors. They act as a reserve of power during periods of no voltage in much the same way that a water reservoir can supply water during dry spells. Continuing with the water analogy, we notice that during the dry spells the water level will fall as water is consumed and this will result in falling …
