Experiments with Higher Electromotive Forces. 



In the experiments dealt with so far the battery nsed to charge the 

 condenser was one of 20 silver chloride cells, hence of electromotive 

 force of abont 20 volts. For electromotive forces between 20 volts 

 and zero Ohm's law is shown to hold good for the liquids experi- 

 mented on. By the following experiments the limits were extended 

 to between abont 100 volts and zero. 



The condenser was charged to abont ] 00 volts, and readings were 

 taken at intervals of 15 seconds, the electrometer having been reset 

 so as to be less sensitive. The ratios are, without any obvious reason, 

 less regular than in the earlier experiments.
