Question

An 8 pole, DC machine has rated current of 100 A. If the armature is duplex lap wound, then the amount of current that will flow in each path at rated condition is ____ A.

• A. 6.25

Answer 1

The correct option is A 6.25
$\text{Duplex lap wound,}$
$\therefore \text{Number of paths = a = mp = 2}\times \text{8 = 16 paths}$

$\text{Current in each path}=\frac{100}{16}=6.25A$
