Thetotal current used, as measured at the generating dynamo,varied between 8 and 16 amperes, the meter rising to 35amperes at the moment of starting, while in smooth runningit oscillates between 8 and 12 amperes. The average energyrequired for working the line and the lighting of the road and the engine, including all losses in the conductor and magneticfriction, is 221) X 10 = volt amperes, or 3 H. P., and,as the motor does H. P. work, the efficiency is 70 percent.
