For every force field in nature there is a corresponding source of that field: gravitational mass is the source of gravitational fields, electric charge is the source of electric fields, electric currents are the source of magnetic fields, quarks are the source of nuclear fields, etc. Further, if there are two such sources in proximity of each ... The diagram shows two charges labeled 1 and 2. The electric field created by the two charges is represented by the field lines also shown in the diagram. View Answer. A metallic sphere is kept is between two oppositely charged plates. The most appropriate representation of the field lines is?
Electric field lines: are always paraliel to the field vectors. are close where the field is strong, far apart where the field is weak. go from positive to negati ve charges. - (1 - Electric fields: important cases Conductors in electric fields The electric field of a point charge is The electric field inside E ~ (KI;I, [away from q if q > 0])
The basic distinction between conduction in metal and in semiconductors is made by considering the energy band occupied by the conduction electrons. It will be recalled that an electric currant is a directed motion of electrically charged particles under the action of an electric field.
