Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
The On/OFF action in UJT is controlled by emitter current
Most multimeter are able to measure resistance.
Current flowing through a device depends on resistance offered by that device.
It is a variable resistance device which control the flow of current
A tunnel diode.
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.

The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
Starting resistance in electrical circuits refers to the initial resistance encountered by a device when it is first turned on. This resistance can affect the flow of current and the performance of the device.
Most multimeter are able to measure resistance.
Plot a V-I curve for an ordinary resistor and you'll get a straight line with positive slope: as current goes up, so does voltage drop across the component. The V-I curve for some semiconductors features a region of negative slope. When the device is operating in this region, it exhibits negative resistance, which can be extremely useful when designing stable feedback systems.
The resistance of a selenium cell or other photoelectric device in total darkness.
A NTC thermistor is a temperature sensor that has a "negative temperature coefficient". That means as temperature goes up, the resistance of the device goes down over it's operating range.
Current flowing through a device depends on resistance offered by that device.
First-person narration is a literary device that deals with blatantly negative language.
