Suppose a digital thermometer works by measuring the voltage across a thermistor (a resistor that i heated or cooled by contact). The thermistor has a temperature coefficient of a = 0.032 °C-1 and reference resistance of 2.6 N at 20 °C, and is part of a circuit designed such that 29.1 mA of curren passes through, regardless of the resistance of the thermistor. How precise* must the voltage measurement of the thermistor be such that the thermometer can detect changes of 0.1 °C? Give your answer in units of mV, and you can assume that the thermistor's dependence on temperature is linear. *1.e., What is the difference in voltage measurements between temperature measurements of, e.g., 37.0 and 37.1 °C?

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
