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

Solution;

Given, that the conductor carries a Dc-current of 5A in one direction & a super-imposed full-wave rectifier in opposite direction.

 The average current is 0.

As it is the full-wave rectifier, the diodes will conduct for the negative half cycle as well.

So;

$\frac{2I_m}{π}-5=0$

$\frac{2I_m}{π}=5$

$I_m=\frac{5×π}{2}=7.854A$
