4 a) Differentiate clearly between “intrinsic conduction” and “extrinsic conduction” in semiconductor materials  b) Doping is a technique used to vary the number of electrons and holes in semiconductors. In your own understanding explain the meaning of the term “doping” as applied to semiconductor materials  c)  An earth satellite has on board 12-v battery that supplies a continuous current of 0.5A. Solar cells are used to keep the battery charged. The solar cells are illuminated by the sun for 12hours in every 24hours. If during exposure, each cell gives 0.5v at 5MA, determine the number of cells required

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.
