Unformatted text preview: at ω). 10. The power that can be mechanically extracted out of an AC motor circuit is Pavg = ¼AIBω. Understand the principles of how the motor works (constant loop of area A in a constant magnetic field B is torqued and therefore spins at ω when a current I goes through it). !" 11. The definition of inductance is L = (metric unit = Henry). !I 12. Inductance of a solenoid of length ! and area A is L = µ N2 A . ! 13. Energy stored in an inductor with current I flowing: E = ½LI...
