If, as is usually thecase, the positive and negative half waves are equivalent, onlyhalf a cycle… … curve and construct a circle JB of equal area, tangent to thehorizontal axis at the origin. This circle is the polar diagram ELECTEO-MOTIVE FOECES AND CUEEENTS 63 of the sine curve having the same Vmean^ value of the equi-distant ordinates as the original curve. Hence the diameter ofthis circle is…
