Abstract
Penfield has noted that circuit theory paradoxically suggests that a series motor connected to a "noise resistor" should run as a perpetual motion machine of the second kind. It is shown that the paradox results because of the incorrect assumption that the noise current at the resistor terminals accounts for the total motor torque.
