en
differential conductance
for a resistive two-terminal element or two-terminal circuit with terminals A and B, derivative of the electric current i in the element or circuit with respect to the voltage uAB (131-11-56) between the terminals:

where the electric current is taken as positive if its direction is from A to B and negative in the opposite case

Note – For an ideal resistor, the differential conductance Gd is equal to its conductance G.

conductance différentielle, f
pour un bipôle résistif, élémentaire ou non, de bornes A et B, dérivée du courant électrique i dans le bipôle par rapport à la tension électrique uAB (131-11-56) entre les bornes:

où le courant est positif si le sens du courant est de A vers B et négatif dans le cas contraire

Note – Pour une résistance idéale, la conductance différentielle Gd est égale à sa conductance G.
