Nonlinear electric flow across parallel plates

The electric current flowing across two parallel plates that touch each other over a circular contact is calculated. The change in the physical properties due to temperature rise caused by Joule heating is taken into account so that the current is not linearly proportional to the voltage difference....

Beschreibung
Zusammenfassung:	The electric current flowing across two parallel plates that touch each other over a circular contact is calculated. The change in the physical properties due to temperature rise caused by Joule heating is taken into account so that the current is not linearly proportional to the voltage difference. The resistance is calculated and an accurate approximation for the resistance, based on minimizing the power, is presented.
