Blem 3.6 solution Problem 3. The figure below shows the field coil of an electric machine. It is excited by closing switch S1 onto an 800V d.c. bus. Determine the energy stored in the coil, and the energy dissipated in the coil resistance, 1 sec after S1 is closed. When the coil current has attained a steady value, S1 is opened and S2 is closed simultaneously. What will be the voltage across S1 0.1 sec later? How much energy will eventually be dissipated in R2?
