An inductor in an electric circuit is essentially a coil of wire in which the voltage is affected by a changing current. By definition, the voltage caused by the changing current is given by V, = L(di/ dt), where L is the inductance (in H). If V, = 15.0- 0.4t for a 3.0-H inductor, find the current in the circuit after 20 s if the initial current was zero. After 20 s, the current is ? A. (Type an integer or decimal rounded to one decimal place as needed.)
