Thermistor Circuit Diagram. A thermistor is a specialized resistor which changes resistance value depending on the amount of heat which it is exposed to. It shows the components of the circuit as simplified shapes and the power and signal friends between the devices.
Voltage divider circuit output is connected to the base of npn transistor through a 1k resistor. The thermistor is made of the semiconductor material that means their resistance lies between the conductor and the insulator. If for example we use a 10kω thermistor with a series resistor of 10kω then the output voltage at the base temperature of 25 o c will be half the supply voltage as 10ω 10ω 10ω 0 5.
These thermistors are basically not used at high temperatures.
In response to the heat it is exposed to it alters its electrical resistances to changes in temperature. Technically all resistors are thermistors their resistance changes slightly with temperature but the change in these. The circuit diagram of thermistor uses the rectangular block which has a diagonal line on it. Working of thermostat circuit.
