Inductors in parallel...

Hi.

Ten equal non-coupled inductances in parallel yield a total of one tenth of the inductance, is that right ?

The power factor correction needed in many factories increases with the number of motors in parallel they operate, is that right ?

Seems the more inductive motors in parallel, the less the inductance, but the need for power factor correction is not less with less inductance.

Where is the catch :confused:

As inductance decreases, current increases in direct proportion. Power is proportional to current, and therefore increases as well.

That explains it; ten motors at say 20 Amperes each is 200 Amperes to account, even for a tenth of inductance. The 200 figure raises the power factor

A single 20 Amperes motor, even having ten times the inductance does not raise the power factor by the same figure product, it is only ~a tenth of the above case.

Then, the amount of inductance in the load is not what makes the bulk of the power factor, the current is... if I got it.

Thanks thingmaker3 !
