 By using two line wires, instead of using the earth as a return circuit. (19) By an adjustable rheostat in the field circuit of the dynamo or in the field circuit of the motor. In the latter case, the adjustable rheostat regulates the dynamo voltage by...  Answers to questionsby International Correspondence Schools - 1901Full view - About this book

...this purpose, though dipping the tops in hot asphaltum will also do. In charging storage batteries, be sure that the positive pole of the battery is connected to the positive pole of the rectifier. This can be found by putting a voltmeter first across the battery and then across the rectifier.... | |
