An ac generator operates at a rotational frequency of 60 Hz and produces a maximum emf of 100 V. Assume that its output at t = 0 is zero. What is the instantaneous emf (a) at t = 1/240 s ? (b) at t = 1/120 s ? (c) at t ? (d) How much time elapses between successive 0- volt outputs ? (e) What maximum emf would this generator produce if it were operated, instead at 120 Hz ? This is problem number 19, chapter 20, in the College Physics book, seventh edition by Wilson, Buffa, and Lou. Thanks for the help. This is my last question for the day.
