A separate excited dc generator turning at 1400 r/min produces an induced voltage of 127 V. The armature resistance is 22 and the machine delivers a current of 12 A. Calculate a. the terminal voltage [V] b. the heat dissipated in the armature [W] c. the braking torque exerted by the armature [Nm] A separately excited dc generator produces a no-load voltage of 115 V. What happens if a. the speed is increased by 20 percent? b. the direction of rotation is reversed? c. the exciting current is increased by 10 percent?
