Question

A conductor carries a current that is equivalent to a 5-amp continuous current in one direction and a superimposed full-wave rectifier current in the opposite direction. What is the maximum value of the latter if the average conductor current is zero?

Answer 1

since average conductor current is zero, then current in the opposite direction:

$I=0.637I_{max}=5$ A

then maximum value of current in the opposite direction:

$I_{max}=I/0.637=5/0.637=7.85$ A
