45. In DC Generators, the armature Emf Ea, is the terminal vot a) Equal to b) Less than More than enough info to answer

Solution

The relation between back Emf Ea and terminal voltage V in a DC generator is

V=Ea-I*Ra where Ra is armature resistance ,I is current through the Armature

We rearrange the equation Ea=V+I*Ra from this we can say as long armature drop is there

the armature Emf Ea ia more than the terminal voltage V
