WebOhmic Conductors R (the slope of the V-I graph above) is a constant for a given conductor under these conditions and is called the resistance. (Unit: Ohm Ω). The circuit element is said to be ohmic, commonly known as an ohmic conductor. 2 necSiP=VI nad V=IR, P=IR= 2 V R. Example 1 Web10 nov. 2024 · 11. 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.
