Q1: In this Zener diode regulator, the source voltage varies from 6 V to 14 V. Assume that the load current  varies between 1 mA and 35 mA, and that the diode is an ideal 4 V Zener diode. What is the largest allowable resistance  that will ensure the load voltage  remains constant with variations in load current and source voltage? Please enter your answer to 3 significant figures.  Q2: Given the circuit design for a Zener diode regulator in the Ques 1, what is the maximum power that will be dissipated by the Rs resistor? You are told that the source voltage Vs  varies from 6 V to 11 V, the load current il varies between 2 mA and 45 mA, and the diode is an ideal 3 V Zener diode. You will need to recalculate the maximum allowable resistance Rs with your new values, as part of this question. Please enter your answer to 3 significant figures, and in Watts.

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.
