Adding a Parallel Capacitor to "Compensate" for an Inductive Load. ... Interestingly enough, "compensation" is an EXACT science, in the sense that," too little" is, actually, the same as "too much". Remember that the inductive and capacitive currents are 180° out of phase and, therefore, "cancel" each other. ...
