1)
Thermistor is
A ceramic semiconductor
None of these
An insulator
A conductor
2)
Regarding Negative temperature coefficient (NTC) thermistor, choose the correct one
Resistance decreases with increase in temperature.
Resistance increases with increase in temperature.
Independent of temperature.
None of these.
3)
Regarding Positive temperature coefficient (PTC) thermistor, choose the correct one
Resistance decreases with increase in temperature.
Independent of temperature.
Resistance increases with increase in temperature.
None of these.
4)
log R-1/T characteristics of thermistor is
Linear
Straight line parallel to x or y axis
Non linear
Parabola
5)
What is the relation between α and β for Thermistor?
β=-α/T²
α=β/T²
α=-β/T²
β=α/T²
6)
Electrical resistance of a thermistor on temperature is given by
R=R₀expα(1/T-1/T₀)
R=βT
R=αT
R=R₀expβ(1/T-1/T₀)
