What happens to the number of free electrons and holes in an intrinsic semiconductor when the temperature decreases?
increases
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
Why is resistivity of a semiconductor higher than that of a metal?
Resistivity is the resistance, in ohms, between the opposite faces of a 1-metre-cube of a material. For metals, resistivity is in the region of 0.0000001 ohm-metre. For semiconductors, it is much higher - it is in the region of 0.01 ohm-metres.
How does resistivity depends on temperature of conductors?
The resistance of a simple conductor normally rises as its temperature rises.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
How are substances classified on the basis of resistivity?
conductor,semiconductor and insulator
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
What happens to the number of free electrons and holes in an intrinsic semiconductor when the temperature decreases?
increases
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What is meant by operating temperature of semiconductor?
The operating temperature of a semiconductor is the temperature at which a semiconductors exhibits the properties of a normal conductor.
Why is resistivity of a semiconductor higher than that of a metal?
Resistivity is the resistance, in ohms, between the opposite faces of a 1-metre-cube of a material. For metals, resistivity is in the region of 0.0000001 ohm-metre. For semiconductors, it is much higher - it is in the region of 0.01 ohm-metres.
What must happen for a superconductor to work?
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area

Is resistivity of a conductor temperature dependent?
