Assume that you are constructing a certain ac circuit on bread board during your lab session. An unknown resistor and an unknown inductor are in series across a 10 V (rms) a.c supply, using a function generator to supply the circuit.When you are adjusting the frequency to 25 Hz the circuit draws a current of 100 mA. When you are increasing the frequency to 75 Hz, it draws 60 mA. Why does it happen so? From this scenario how would you obtain the values of unknown circuit components.Justify your answer mathematically.

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.
