How does a capacitor smoothens a voltage and how does an Inductor smoothen the current Take a large reservoir of water. Does the inlet of water increase the water level suddenly? No. Watertank analogy of a capacitor: Does the outlet of water suddenly decrease the water level? No. A capacitor is like a water tank. Inlet water is like a charging current. The outlet of water is like a discharge current. Water level is like the voltage of a capacitor. DC ripple filter: The process of how a capacitor maintains its voltage level is best explained by how a filter capacitor smoothens the DC ripple. When the incoming voltage increases, it charges to that voltage. When the incoming voltage decreases, it uses its stored energy to supply current to the load by maintaining the voltage level. As long as demand le less than supply, it comfortably maintains almost a constant level of voltage across the load. That is exactly what an overhead water tank in our home does when there is an irregular water ...
