Why do we use capacitor in rectifier circuits?

Capacitor is basically a charge-storing element. Output of rectifier need to be regulated over a specific voltage range for regulator circuit to get DC output further. Observe this diagram. A capacitor of say 1000uF will charge as the voltage incr... read more

This the reason we use Capacitor Filter for Rectifier circuit. For more details on Series Capacitor Filter, please visit: Shunt Capacitor Filter.

Capacitor used for charging and discharging of electric field.(e.g, rectifier circuits) It also used for filtering actions in passive filter circuits. read more

Capacitor discharge current: On the discharge cycle, the maximum current supplied by the capacitor occurs as the output from the rectifier circuit falls to zero. At this point all the current from the circuit is supplied by the capacitor. This is equal to the full current of the circuit. read more
