A 0.250-H inductor carries a time-varying current given by the expression I=4sin2t Find an expression for the induced emf as a function of time. Graph the current and induced emf as functions of time for to (b) What is the maximum emf? What is the current when the induced emf is a maximum? (c) What is the maximum current? What is the induced emf when the current is a maximum?
