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.)

You are a journeyman electrician working in an industrial plant. Your task is to connect an inductor to a 480-V, 60-Hz line. To determine the proper conductor and fuse size for this installation, you need to know the amount of current the inductor will draw from the line. The nameplate on the inductor indicates that it has an inductance of 0.1 H. An ohmmeter reveals that it has a wire resistance of 10 . How much current should this inductor draw when connected to the line?
