The Lowering of The causes of the decrease in of the valves may besummed up as follows: 1. Ohmic resistance produced at the opening of the valves bythe film upon the anode. 2. Ohmic resistance of the film at the cathode. 3. Effects of static charge during the periods of opening andclosing. 4. Non-uniform composition of the anode. Electric Motors. Electric motors, when operated by this current, behave in amanner similar to that considered in connection with a singlevalve. Motors, with their field magnets excited by current froma storage battery, operate excellently and give a high efficiency. Fig. 8. as a result of the absence of the inductive influence of their fieldcoils. Such motors should have their iron parts finely laminated^as in the Rechniewski motors, in order to obtain this 8 shows the behavior of a small Edison shunt-wound is the current, U the alternating potential difference, and U^the of the rectified current. The current shows itself as aflat curve, but the cuts the axis at each half cycle. Thereresults a lowering of the efficiency and sparking at the brushes. Storage Batteries on Bectified Currents. A lead accximulator can be compared to an electrolytic con-denser of large capacity in which tlie charge disappears as fast as 524 NODON: ELECTROLYTIC RECTIFIERS. it flows in and is reproduced as it flows out owing to internalchemical reactions. Considered in this way, it will be seen thatthe accumulator, with current rectified by valves, can produ
