Study Notes
Thermistor Circuit and Measurement
- Ohm's Law is used to calculate the resistance of the thermistor with the equation: ( R = \frac{V}{I} ), where ( R ) is resistance, ( V ) is voltage across the thermistor, and ( I ) is the current through it.
- In the thermistor circuit, the voltmeter is wired across the thermistor to measure the voltage drop across it.
- The ammeter measures the current flowing through the thermistor circuit, providing insight into the electrical flow and allowing resistance calculation.
Temperature Variation and Measurement Range
- Temperature of the thermistor resistor can be varied by placing it in different environments, such as ice water, boiling water, or room temperature settings.
- Recommended temperature range for making measurements with the thermistor typically spans from -20°C to 100°C, allowing for diverse experimental conditions and data collection.
