(L11) The current flowing through a 3.64E-3 H inductor increases from
3.50 A to 9.62 A. What is the work done by the current to the inductor (in
J)?
A 90 mH inductor carries a current that varies with time according to the equation:
The voltage across an inductor is proportional to the inductor and the derivative of the current that flow through it.
