A. No, a digital thermometer is not a form of mercury thermometer.
Digital thermometers use electronic circuits and devices to show temperature measurements.
These thermometers display the measurements as numbers. Digital thermometers measure temperature by means of a slender device called a probe. The probe is made of either a metal, such as copper or platinum, or a semiconductor. Temperature changes cause a large variation in the electrical resistance of these materials. Most semiconductors are more sensitive to temperature changes than metals.
