The voltage V produced by an alternating current generator is V (t) = 229 sin (120mt) . What is the period of V(t)? When does the generator reach the maximum voltage for the first time? A) period: 1/60; maximum voltage at f = 240 B) period: 1/120; maximum voltage at f = 240 C) period: 1/60; maximum voltage at f = 120 D) period: 120x ; maximum voltage at f = 240 E) period: 1/60; maximum voltage at ( =_ 80 F) None of these
