1 Le Chateliers Principle and catalysts. Catalysts have sneaked onto this page under false pretences because adding a catalyst makes absolutely no difference to the position of equilibrium and Le Chateliers Principle doesnt apply to them. This is because a catalyst speeds up the forward and back reaction to the same extent

The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field it experiences a mechanical force. The direction of the mechanical force is given by Flemings Left-hand Rule and its magnitude is given by F BIL Newton. The working of the AC motor Induction motor and Synchronous Motor
