A circuit consisting of a Negative Temperature Coefficient (NTC) thermistor and a fixed resistor is connected in series with a DC power supply. If the output voltage is measured across the fixed resistor, what change will occur in this output voltage as the temperature of the thermistor increases?
- 1The output voltage will remain constant.
- 2The output voltage will decrease.
- 3The output voltage will increase.✓
- 4The output voltage will fluctuate randomly depending on the tolerance of the resistor.
Correct answer
The output voltage will increase.
