Answer to Question #307319 in Electrical Engineering for Pusha

Question #307319

A DC generator has 136 conductors in series. Each has an effective length of 15 cm, is constrained to move in a circular path of radius 12cm and lies in a uniform Field flux density 1.2 Tesla.


Calculate the emf generated when armature rotates at 1400 rpm



b) A coil of 2500 turns has a flux of 10mWb linking with it when carrying a current of 2A.


Calculate the coil inductance and the emf induced in the coil when the current collapses to zero in 20 ms
