Question: Where to find Section 8.7?
Answer: Good call. You can find what that was supposed to be in this section: Mechanical Electric Theory#Result #7: Efficiency of converting electrical energy into mechanical energy increases with the RC time constant and the angular velocity of charges. The angular velocity was specific to be that of the charges in question, not of the angular velocity of the rotor. Likewise, the torque is that of the charges as well.Kmarinas86 03:01, 9 November 2008 (UTC)
