Formula for cancellation of reactance voltage on an average basis using interpoles ________$

A. 2[B<sub>i</sub>(av)l<sub>i</sub>v<sub>a</sub>] N<sub>c</sub> = L<sub>c</sub> (di<sub>c</sub>/dt) = L<sub>c</sub> (2l<sub>c</sub>/t<sub>c</sub>)
B. [B<sub>i</sub>(av)l<sub>i</sub>v<sub>a</sub>] N<sub>c</sub> = L<sub>c</sub> (di<sub>c</sub>/dt) = L<sub>c</sub> (2l<sub>c</sub>/t<sub>c</sub>)
C. 2[B<sub>i</sub>(av)l<sub>i</sub>v<sub>a</sub>] N<sub>c</sub> = L<sub>c</sub> (di<sub>c</sub>/dt) = L<sub>c</sub> (l<sub>c</sub>/t<sub>c</sub>)
D. Cannot be determined
Answer» B. [B<sub>i</sub>(av)l<sub>i</sub>v<sub>a</sub>] N<sub>c</sub> = L<sub>c</sub> (di<sub>c</sub>/dt) = L<sub>c</sub> (2l<sub>c</sub>/t<sub>c</sub>)
