What happens to the potential difference for example in a thermistor when the current is increased? The main question is does $V=IR$ apply to a non-ohmic conductor?

Best Answer
The relation $$V=IR$$ also holds for a non-ohmic conductor (resistor). The only difference to an ohmic conductor is that the resistance $R$ is not constant but can depend on current $I$, voltage $V$, or even on time.
