AI Thread Summary
Ohmic conductors can be transformed into non-ohmic conductors by increasing temperature or altering electrical conditions. Most metals exhibit ohmic behavior below approximately 1000°C, transitioning to non-ohmic as temperature rises. Traditional filament light bulbs demonstrate non-ohmic behavior due to increased resistance as the filament heats. In transistors, the conductor behaves ohmically without base current, switching to non-ohmic when the base current is applied. Similarly, an electric motor's armature is ohmic when stalled but becomes reactive upon release.

How to change an ohmic conductor to a non-omic conductor over a short period of time
Most metals show ohmic behaviour below about 1000C, raise the temperature and the behaviour is non - ohmic. Traditional filament light bulbs show non - ohmic behaviour, the resistance increases as the filament heats up at switch on.
 
The conductor can be the output of a transistor. Without base current, the conductor will be ohmic.
Close the switch and it will be non-ohmic.
Or, if the conductor is the armature of an electric motor, and the shaft is prevented from turning, it will be ohmic.
Release the shaft and it will be reactive.

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
