Thermistor is a thermally sensitive resistor. The Thermistor is a two-terminal component that may be used in either AC or DC circuits. It is manufactured in a number of shapes, such as beads, rods, disks, washers and flakes. Thermistors are often part of sensor devices used in temperature control. Flow measurement, voltage regulation, and such.
Using this trainer, it is possible to study and (a) observe the self-heating effect of current on the resistance of a Thermistor. (b) To determine experimentally the variation in resistance with time of current in a Thermistor (c) To study the Dynamic Characteristics of Thermistor.
This trainer has built in power supplies, Thermistor. It is desired to have additional 100mA DC current meter and high input impedance DMM for measurements.
