and is increasing at the rate of 100 mA/s. a.) What is the initial energy stored in the inductor if the inductance is known to be 61.0 mH? Jb.)How long does it take for the energy to increase by a factor of 10 from the initial value? s
If you look up inductor on Wikipedia, you'll find that. E?LI? Where Eenergy LInductance Icurrent So finding the energy isn't hard. To find the time for part b, first find the current needed for 10 times the enrgy (also using E?LI?, but this time with 10 times the energy). Then, if we assume that the rate of increase is constant (seems to be true from the problem statement) finding the time is a matter of dividing the current difference by the rate of change (the 100 mA/s).
