ANGLE OF ELECTRICAL 

 FIELD (Degrees) 



Figure 12. — The effect of the angle of electrical field in relation 

 to electrode spacing tising 2-inch electrodes at a width 

 ct electrical field of 3 feet with a voltage gradient 

 of 1 volt/cm., a pulse frequency of 8 pulses/sec, a 

 pulse duration of kO milliseconds^ and a square wave 

 form.
