Case V. — The constants for this case were : 

 Li = 0-1974 henries. 

 L 2 = 2350 



Ci = 15*95 microfarad. 

 O 2 =-0000335 „ 

 P =0-8142. 

 M=19'44 henrios. 

 E 1 = l-90 ohms. 

 R, = 38000 „ 

 i =4*3 amperes. 



The expression (2) gives for the frequencies 



™ 1 = 88-98, n 2 = 1329*3. 



By (1) the secondary potential is 



2Y 2 = 46950e- 465 ^ sin (32033^-0-05) 



- 3143 *-«*» sin (478548* -0-8). 



The curve representing the square of this expression is 

 shown in fig. 5, and its maximum value is 48960 volts. The

photograph is given in Plate XIII. fig. 12, but it should be 

 stated that the amplitude of the short wave varied consi- 

 derably in different photographs, it being sometimes larger, 

 sometimes smaller than is here shown. As in some other 

 cases, these variations appear to arise from irregularities in 

 the action of the interrupter.
