Why electric field lines are always normal to the conductor?

Because electric field lines must be perpendicular to the surface of conductor, otherwise there would be a non zero component of electric field along the surface of conductor and charges could not be at rest.

What is the difference between electric field and electric field lines?

The Basic Difference between electric field and electric field intensity is that, The electric field is a region around a charge in which it exerts an electrostatic force on other charges. While the strength of the electric field at any point in space is called electric field intensity. It is a vector quantity.

What is the formula of electric field?

In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.

What is electric field and its physical significance?

An electric field is an elegant way of characterizing the electrical environment of a system of charges. The electric field at any point in space around a system of charges represents the force a unit positive test charge would experience if placed at that point.

What is the relationship between electric field and electric flux?

Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.

What do you mean by electric field lines?

Electric field lines in an electric field are imaginary lines, the tangent to which, at any point, gives the direction of the electric field intensity. In simpler version, it can be said, an electric field line is a path along which a positive charge would move, if it is free to do so.

Where is an electric field the strongest?

The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.

Where are electric field lines strongest?

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

What best describes an electric field?

The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point.
