with each pulsation varying fromzero to a positive maximum. Such a current could not bemaintained by the rectifier, because as soon as the zerovalue was reached the negative electrode resistance of therectifier would be re-established and the circuit wouldbe broken. To avoid this condition,… … Fig. 118 value. The overlapping of the rectified current wavesreduces the amplitude of the pulsations and produces acomparatively smooth direct current as shown in curve III.The complete circuit of a type Ai rectifier outfit isshown in Figs. 118 and 119. The alternating currentsupply circuit is…
