Definition:  under sinusoidal conditions, circuittheory theorem stating that, when the value of the impedance of a branch of a passive linear network is changed, the electric current change in any branch is equal to the current that would be produced by a source voltage inserted in the modified branch, the value of which is the product of the current in this branch before the impedance is changed by the impedance change
NOTE – The compensation theorem can be generalized to nonsinusoidal conditions.
