Actually it depends on the material from which the resistor is made, well in general for all practical purposes we choose a material with positive temperature coefficient as we deliberately want to add a resistance to the circuit.
But if we come across some resistors which are made up of materials like Glass, Ceramics, Semiconductors , have negative temperature coefficients (practically not used)
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
negative tempareture It depends on the reverse voltage. Up to about 5.6 volts, the zener has a negative temperature coefficient. Beyond 5.6 volts it begins to show a positive temperature coefficient.
negative temperature coeeficient
Yes, carbon has a negative temperature coefficient. -0.5*10^3/C
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
negative 'temperature coefficient of reactivity'
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.

what type of question is that
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
the sensistor functions as a temperature sensitive resistor with a positive coefficient of temperature.used for temperature compensation in various circuits
yes, calculate it from temperature coefficient of resistance.
