a separate excited dc generator turning at 1400r/min produces an induced voltage of 120v. The armatureresistnce is 2 ohms and machine delivers a current of 12A. what is the terminal voltage? the heat dissipated by the armature? the braking torque exerted by the armature?

Step 1

Given:

DC generator speed, *N* = 1400 rpm

Induced voltage, *E _{a}* = 120 V

Armature resistance, *R _{a }*= 2 Ω

Armature current, *I _{a}* = 12 A

Step 2

Write the expression for the terminal voltage and calculate it.

Step 3

Substitute the known parameters,
