    Coloumb’s law has the following three limitations:

    • The charges should be point charges i.e the charges are placed at a point which have no dimensions
    • The second limitation is the distance between the two charges remains constant.
    • The third limitation of Coloumb’s law is that the charges should not radiate any amount of energy. For eg in Bohr’s postulate, Coloumb’s law is applicable to the electron moving around the nucleus as it is assumed that the electron does not radiate any energy.

    It is only applicable for charges which are at rest and it is only applicable for point charge

    The ability of an capacitor to store the energy in form of electric charge is known as Capacitance.

    In other words capacitance can be described as the storing ability of a capacitor and it is measured in farads.

    For Example, if we connected a capacitor to a 9 volt battery and measured that it stored 9 coulombs of charge, its capacitance would be 1 farad

    It is an imaginary line which describe the direction of electric field. It may be curve or straight. It orginated from positive charge and terminated at negative charge. It don't form close loop

    0Thank You

    Harsh Pahuja 6 years, 5 months ago

    Electric field lines are imaginary lines which tells the direction of the field lines (i.e from +ve to -ve) for isolated -ve charge it moves from infinity to the space near the charge and vice-versa for +ve charge.

    ✴️ The flux of electric field through any closed surface S is 1/ε0 times the total charge enclosed by S. ✴️ Electric field outside the charged shell is as though the total charge is concentrated at the centre. The same result is true for a solid sphere of uniform volume charge density. ✴️ The electric field is zero at all points inside a charged shell
