Question

In an A.C. generator, increase in number of turns in the coil _________

(a) Increases emf

(b) Decreases emf

(c) Makes the emf zero

(d) Maintains the emf at a constant value

I got this question during an interview for a job.

Query is from Generation of an Alternating EMF in portion Alternating Voltage and Current of Basic Electrical Engineering

Answer 1

Right option is (a) Increases emf

The explanation is: In an A.C. generator, the emf increases as the number of turns in the coil increases because the emf is directly proportional to the number of turns.
