WebOhm’s Law. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is electric potential difference, and R R is resistance. WebJul 27, 2015 · When temperature rise, the internal resistance of material rise because the atom have more kinetic energy therefore, electrons ( current) got more difficulty to flow. That explain the change of function in the most part because there is a resistance internally in a diode. – MathieuL Jul 27, 2015 at 15:44 Add a comment 4 Answers Sorted by: 7
