1. A 109.3 mH inductor whose windings have a resistance of 3.6 Ω is connected across a 11 V battery having an internal resistance of 1.83 Ω. How much energy is stored in the inductor?
2. The maximum allowable potential difference across a 225.7 mH inductor is 401 V. You need to raise the current through the inductor from 1.28 A to 3.88 A. What is the minimum time you should allow for changing the current?
N=number of loops
The Attempt at a Solution
For both of these what seem to be similar problem I am hitting a dead end!
