Consider the configuration shown in the figure: An in- finite plane conductor has a small hemispherical knob of radius a as indicated. A point charge q is placed directly to the right hand side of the hemispherical knob at a distance b from its center. Assume that the boundary, i.e. the infinite plane with the knob, is kept at zero potential. a) Find the potential p at a generic point P on the right hand side. b) Determine the appropriate Dirichlet Green function for this geometry and write down the most general solution of the potential p given a generic charge density p on the right hand side of the boundary and that potential p = f("r) on the boundary. %3D c) Find the total charge induced on the knob. P(r) a b

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.
