Two Mathematical Comments on the Thevenin Theorem: An “Algebraic Ideal” and the “Affine Nonlinearity”

<div>An equivalent circuit, with Zener-diode, if the external circuit with a stronger battery (applying its voltage as shown, the plus up) uses our Thevenin circuit as a load. (Notice the direction of the current.)</div>
