Yes, Thermistor is the right answer.

@Shreedhar is right,

The kind of thermistor may be what ever, but both NTC and PTC sensitive to temperature.

Shreedhar K S said:   6 years ago
ANSWER - Thermistor is right.

Yes, right @Yogesh & Ravikumar.

They asked only which is temperature based resistor, NTC and PTC both are temperature based thermistor resistors it may be an NTC or PTC.

Thermistors are two opposite fundamental types:

1) NTC- Negative Temperature Coefficient. If here temperature increases resistance decreases.

2) PTC- Positive Temperature Coefficient. If here temperature increases resistance also increases.

NTC thermistors decrease in resistance as the temperature increases. PTC thermistors are Positive Temperature Coefficient resistors generally made of polycrystalline ceramic materials that have a high positive temperature coefficient, which increases in resistance as the temperature increases.

Thermal is the measure for Energy (heat or Cool).

Thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiter, temperature sensors. Thermistors are of two opposite fundamental types:.

With NTC, resistance decreases as temperature rises to protect against inrush overvoltage conditions. Commonly installed in parallel as a current sink.

With PTC, resistance increases as temperature rises to protect against overcurrent conditions. Commonly installed in series as a resettable fuse.

Thermister is positive temperature coefficient. Its resistance varies with temperature.

Yes, @Manoj is correct.

Gopal said:   9 years ago
Because thermister having thermal property and which the component very sensitive due to some radiation which is by using anti static room.

Temperature =1/resistor.
