loss of free current carriers as temperature drops.
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
A: As temperature increases its resistance increases. Like all silicon diodes it will reach a point where the temperature coefficient is zero but it is at such elevated temperature to make it invaluable
Electrical resistance increases because the density of charge carriers decreases with increased temperature. High temperature resistivity is predominantly characterized by collisions between electrons and metal atoms. Decreasing the density of charge carriers increases resisistance.
NO. In a semiconductor the resistance decreases with increase of temperature. It is their natural behavior unlike conductors and insulators. If we decrease the temperature their resistance increases. At 0 degree kelvin all semiconductors will act like perfect insulators.
The resistance of the copper piece will increase, while the resistance of the germanium piece will decrease as they are both cooled from room temperature to 800 K. This is because the resistivity of metals like copper generally increases with decreasing temperature, while for semiconductors like germanium, the resistivity decreases with decreasing temperature.
In NTC (Negative Temperature Coefficient) resistors, as the temperature increases, the number of charge carriers also increases. This results in more electron movement, decreasing the resistance. The relationship between temperature and resistance in NTC resistors is inversely proportional.

Some materials with a positive temperature coefficient of resistance include silicon, germanium, and thermistors made of certain metal oxides like manganese, cobalt, and copper. These materials exhibit an increase in resistance with an increase in temperature, making them useful in temperature-sensing applications.
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
most metals resistance increases with temperature
As the resistance increases the temperature will also increases....
Fraction increases with decreasing temperature.
It increases

Yes, that's correct. In a thermistor, which is a type of temperature-sensitive resistor, the resistance decreases as the temperature increases. This is because the conductivity of the thermistor material increases with temperature, causing the resistance to decrease.
