A. Determine the self-inductance of a coil which produces 5V when the current changes from 3A to 2A in one millisecond. B. The current in an inductor is changing at the rate of 100 A/s, and the inductor emf is 40 V. What is its self-inductance? C. When a current of 2mA is supplied to a coil with 100 turns, a magnetic flux of magnitude 200mWb is linked with it. Find the self-inductance of this coil. D. A magnet from which emanates 800 maxwells of flux is inserted through a coil of 1000 turns. It is withdraws within 0.15seconds. What is the voltage induced across the coil? (Note 1 Weber = 1x10 Maxwell)
