The function for a current is /(t) = 9cos 120nt where / is the current, in amperes, and t is the time in seconds. a) Find the current when t = 6 s. b) The electromotive force, E(t), in a circuit, is given in volts by finding the first derivative of the current function /(t). Find the function for the electromotive force E(t).
