Electronic thermometers measure temperature and display results how?

Analog Dial Thermometers Mercury-in-Glass Thermometers Digital Electronic Thermometers Bimetal Strip Thermometers

Correct Answer:

Digital Electronic Thermometers

Explanation:

Electronic thermometers rely on a sensor whose electrical property changes with temperature (like a thermistor or RTD). The sensor’s signal is read by a microcontroller, which converts it into a numeric temperature value and drives a digital display (LCD/LED). So you get a direct numeric readout in Fahrenheit or Celsius. This is different from devices that show temperature with a moving needle, a mercury column, or a mechanical bimetal strip, all of which present information through physical movement rather than a digital value.
