Two coils of self inductance L1 and L2 are in parallels as shown in fig. If their Mutual inductance is M, then the effective inductance will be given by
|
$\frac{L_1 L_2 }{L_1+L_2+2M}$ $\frac{L_1 L_2+M^2 }{L_1+L_2-2M}$ $\frac{L_1 L_2 - M^2 }{L_1+L_2-2M}$ $\frac{L_1 L_2 -M^2 }{L_1+L_2+2M}$ |
$\frac{L_1 L_2 -M^2 }{L_1+L_2+2M}$ |
When two inductances are in parallels then $L = \frac{L_1 L_2 -M^2 }{L_1+L_2+2M}$
