is perhaps as good as could be expected for the two highest curves, a 

 substantial divergence is noticed in the two lowest sets ; the forms of the 

 two sets are significantly different, and it seems that the divergence 

 might become even greater at larger values of npdRi than those 

 shown. Upon examination of the equations, however, it turns out that 

 the conditions existing for the lowest pair of curves are just those for 

 which recharging occurs, so that the conditions for which the equations 

 were framed hold no longer. The calculated distributions might be 

 expected to be too low for the higher harmonics, since we have taken an 

 average value for the saturation inductance. This means that the peak 

 of the discharge pulse will be sharper than that calculated, with a 

 corresponding effect upon the higher harmonics.
