then consulted to select the next higher value of the capacitor available in the
               market.


               Example 15.6   A half-wave capacitor filter rectifier has maintained an

               average output voltage of 15 V with a peak to peak ripple of not more than 3
               V. The load resistance is 100 Ω Calculate the value of the capacitor filter.

               The ac supply frequency is 50 Hz.


               Solution:


               The load current,












               Time period,












               The time of discharge of the capacitor t  can approximately by considered
                                                               1
               equal to T. Therefore,

                                                     t  = T = 20 ms
