Parallel Configuration
Several inductors can be connected in parallel to decrease inductance. This image shows inductors in series:
 * [[Image:Inductors_in_Series.svg|300px]]

The formula for the total inductance is


 * $$\frac{1}{L_t} = \frac{1}{L_1} + \frac{1}{L_2} + ... + \frac{1}{L_n}$$

When you connect two inductors of the same inductance in parallel, the total inductance is halved.
