A thermometer is initially at a room temperature of 25°C. At a time t =  0, the thermometer is dipped in a boiling water bath having a temperature  of 80°C. The thermometer is a first-order system with a time constant of  5.5 s. Plot the temperature reading versus time, showing in particular the  10-s reading. At what minimum time the thermometer will be within 10% of  response from the steady-state value?

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.
