What happens to the peak electromotive force (e.m.f.) and to the period of the a.c. output when the coil is rotated slower?

A

Peak e.m.f. is smaller, period is longer

B

Peak e.m.f. is smaller, period is shorter

C

Peak e.m.f. is greater, period is longer

D

Peak e.m.f. is greater, period is shorter
