In a graph between current i and voltage v, find the portion corresponding to negative resistance.

Considering that the temperature and physical conditions are constant, Ohm’s law claims that the flowing current via any conductor is directly proportional to the potential difference across the ends. Ohm’s law can be described mathematically as:

V = IR

Here,

V = Voltage
I = Current
R = Resistance

Solution of the Above Equation

Thus, Negative resistance = – (V/I) = [V/(– I)]

Therefore, the part is CD where resistance is negative.
