For an SCR the average & rms values of current are I/4 & I/2 respectively. Calculate the average on-state current rating (ITAV). Take maximum RMS on-state current = 35 A.

For an SCR the average & rms values of current are I/4 & I/2 respectively. Calculate the average on-state current rating (ITAV). Take maximum RMS on-state current = 35 A. Correct Answer 17.5 A

Form factor = RMS/Average vaules of current Therefore, FF = 2 ITAV = 35/2 = 17.5.
