Why the electric field just outside the conductor is perpendicular on its' surface?

If it isn't perpendicular, the charges would be redistributed because there would be force component tangential to the surface. In other words, the charges would move to a new equilibrium position, in which the electric field IS perpendicular to the surface.

∙ 11y agoThey are not always perpendicular! Only vacuum radiation fields (TEM/TE/TM) waves satisfy this property. There are also absolutely parallel stationary E/M waves (Non-Null Fields in relativistic terminology) with a characteristic screw-like geometry of field lines that are mixtures of left and right polarized modes (Helicoidal eigen-states) that have been also experimentally constructed inside laser and other cavities.

Why electric field lines are always perpendicular to the surface of the conductor?
to save the static character of conductor in the presence of electric field
What are three facts about electric field lines?
1. Electric field lines of force originate from the positive charge and terminate at the negative charge. 2. Electric field lines of force can never intersect each other. 3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero. 4. Electric field lines of force are always perpendicular to the surface of conductor. 5. Curved electric field lines are always non-uniform in nature.

Electric charge is uniformly distributed on the surface of a spherical balloon. Show how electric intensity and electric potential vary (a) on the surface (b) inside and (c) outside?

What is the electric field on the surface of the conductor?
The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy. But when you measure the electric field inside a charged sphere, the charge you use might be large enough to redistribute the surface charge. In this case the electric field will not be zero. Only if you measure at the centre.

Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.

What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.

What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal
What is the properties of material that is durable and conductor of electricity?
There is no electric field inside a conductor.Otherwise, the charges in the conductor would move.Charges exist only on the surface of a conductor.Otherwise, there would be electric fields inside.All points of a conductor are at the same potential.Since DV=-EDx, since E=0, the potential must be constant.
Does charge get redistributed over the surface of conductor why?
You need to define your querstion a little more. Are we talking about an electric current, or a static charge?
If a conductor is placed in a uniform electric field does the conductor gain any charge?
The conductor will not gain any charge that is not placed on it by you. However, the electric field will displace the free charges already within the conductor (by its nature) such that there will be a non-uniform surface charge density. Remember: a conductor must have zero electric field inside it, so the charges rearrange to cancel the external E-field. Again, this only repositions the existing charge, but it does not add or remove any charge.

The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy.

Why 400kVA and above the transmission line have bundled conductor?
To reduce the electric field intensity at the surface of the conductor which can lead to corona discharge and insulation breakdown. By using bundled conductors, the electric field is distributed between the four (in the case of 400-kV lines) conductors, thus reducing the field intensity per conductor.
