Diodes do not follow Ohm's Law. But. At any given current level, you can measure the change in voltage ( Δ V) for small changes in current ( Δ i ), and get a local equivalent resistance called dynamic resistance. Graphically, this is simply the slope of the voltage/current curve for the diode, or R d = Δ V Δ i.

Web24 jul. 2024 · Updated on July 24, 2024. The basic laws of electrical circuits focus on the basic circuit parameters of voltage, current, power, and resistance. These laws define how each circuit parameter is interrelated. These laws were discovered by Georg Ohm and Gustav Kirchhoff, and are known as Ohm's law and Kirchhoff's laws. Wikimedia Commons.
