dinates characteristic of this machine is wonder- should correspond to the tangent of the fully straight. In a " D2 " machine, wound angle of slope of this potential curve — in for a potential of 60 volts, the following other words, if we were to differentiate values were obtained. Open circuit, 58… … Diagram of Potentials at Collectoe of 4-Pole Schuokekt-Mokdey Dynamo. and a negative maximum at about 120°, amperes, 59.9 volts; 120 amperes, 60 volts. It will be seen that for small where the slope up and slope down are steepest in the potential curve. These loads the potential drops a little ;…
