Re: Re: DC behavior with AC TC




  Robert -

  Thank you for correcting my statement. I had forgotten that the VdG
terminal could be positive by removing electrons from the terminal. The work
(energy) would be

  Joules = Q x V

  Can this equation be related to the motor to show that the belt motor
would slow down as the voltage builds up on the terminal? The charge would
be zero on the inside of the terminal.
