A shunt generator running at 1000 r.p.m. has generated e.m.f. as 200 V. If thespeed increases to 1200 r.p.m., the generated e.m.f. will be nearly
A)150 V
B)175 V
C)240 V
D)290V

Question

Quizplus · Accepted Answer

The generated e.m.f. in a shunt generator is directly proportional to the speed of rotation. Therefore, if the speed increases from 1000 r.p.m. to 1200 r.p.m. (a 20% increase), the e.m.f. will also increase by 20% from 200 V to 240 V.
