Electric Lines of Force   (1) Definition : The electric field in a region is represented by continuous lines (also called lines of force). Field line is an imaginary line along which a positive test charge will move if left free. Electric lines of force due to an isolated positive charge, isolated negative charge and…

Electric Potential (1) Definition of Electric Potential.: Potential at a point in a field is defined as the amount of work done in bringing a unit positive test charge, from infinity to that point along any arbitrary path (infinity is point of zero potential). Electric potential is a scalar quantity, it is denoted by V;…
