Energy in an Inductor. When a electric current is flowing in an inductor, there is energy stored in the magnetic field.Considering a pure inductor L, the instantaneous power which must be supplied to initiate the current in the inductor is . so the energy input to build to a final current i is given by the integral
*The resistivity of semiconductors depends strongly on the presence of impurities in the material, a fact which makes them useful in solid state electronics.. References: 1. Giancoli, Douglas C., Physics, 4th Ed, Prentice Hall, (1995). 2. CRC Handbook of Chemistry and Physics, 64th ed.
