In a particular inductor, the magnetic flux through each of its 85 turns is measured to be 3.30 milliWeber when the current through the inductor is 1.60 Amperes. After making this measurement, the current through the inductor is then varied as i(in Amperes) = 1.60 + 3t 5/3 - 2 t2 (where t is in seconds). What is the average emf across the inductor between two and three seconds? What is the energy stored in the inductor when t...
