{title2=$R_{\mathrm{th}}=-dV/dI$}

The negative slope of the <Thévenin terminal response> with delivered <electric current> $I$. <Thévenin source suppression> determines it from the ratio of test voltage to entering test <electric current>. It need not represent a physical positive <resistor> inside the original network.
