Start by working out the inductive reactance of the load,
XL=2x3.14xFxl. result is in ohms.

Now to counter act this you need a capacitive reactance
of simular size.

XC= 1 / 2x3.14xFxC.

So work out what capitance will provide the required amount
of capacitive reactance.

Not easy but do - able.


So the correction capacitor/s sit across the mains line,
And provide a simulair but reverse amount of reactance.
equal and oppisite cancell out.

Inductive and capacitive reactance tend to cancel ohm for ohm....
