A dc generator built for a higher voltage than another of the same power will have
Answer: D
Correct answer: more turns of finer wire in its armature winding
For a given power, a higher voltage means a proportionately smaller current. The winding must therefore develop more volts, which needs more conductors in series, and it carries less current, so each conductor can be of smaller cross-section. Hence more turns of finer wire - and, for the same reason, a wave winding rather than a lap winding, since wave puts \( Z/2 \) conductors in series against lap’s \( Z/P \).
