In my graphs have some points did not on the best-fit line. It could be read the voltmeter or ammeter not ready correct have some error. And than the thermometer is not ready measuring the thermistor.

Because the thermometer did not close the thermistor. So I should use the stand to keep thermometer close the thermistor.

A thermistor is a type of temperature-sensitive resistor, meaning that its resistance is affected by a change in temperature.

Thermistors can be categorised by their temperature coefficient of resistance, which is ratio of increase in resistance to its resistance temperature rise.

They offer mechanical, thermal and electrical stability, together with a high degree of sensitivity.

The next question is, how does an NTC thermistor work?

When the thermistor is subjected to a change of temperature of 80The resolution is the smallest change it can detect in the quantity it is measuring, or the precision with which the measurement can be made.

When performing the experiment, the voltage value on the multi-meter constantly fluctuated, therefore an average had to be taken.

Atoms that we might vaguely remember from our Chemistry lessons make up everything and these in turn are made from electrical particles. The tiniest of these and the ones which move inside wires and electric circuits are called Electrons. or direct current and here the electrons can only flow in one direction through the circuit from out from one pole of the battery, called the negative and back in to another pole of the battery called the positive.

There are subtle differences however between electricity from the mains and a battery of whatever type, wet and containing acid as in car, or dry and containing a special jelly-like material as in say our digital camera. They were very misguided but in their infinite wisdom decreed that D.
