Any net charges reside on the surface. 4. The surface is always equipotential. 5. The field just outside is zero. Which of the above statements are correct? Correct Answer 1, 2, 3 and 4

Ideal Conductor:

The ideal conductor needs a very small amount of potential difference (voltage) to carry on an extremely high current. That means it has infinite conductivity and zero resistance. The voltage drop is also zero. This type of conductor generally not exist.

Properties of ideal conductor:

  • The electric and magnetic field (i.e. net field) inside the conductor is zero.
  • The net charge density inside the conductor is zero and any net charge resides on the surface of the conductor.
  • An ideal conductor always has an equipotential surface.
  • Outside the conductor, there is a field present.

Lightening conductors are used to protect building from lightning strikes. Which of the following statements is/are true about lightening conductors? 1) Lightening conductors create an electric field at its top that lightning strikes it preferentially 2) Lightning conductors reduce the effect of the strike by uniformly distributing the charge (current) over the surface of the building 3) Lightning conductors take all the charge (current) to deep down in the earth 4) Lightning conductors must be installed at a place taller than the building Select the correct answer using the code given below
The solutions to many problems involving electric fields are simplified by making use of equipotential surfaces. An equipotential surface is a surface: 1. On which the potential is the same everywhere 2. The movement of charge over such a surface would require no work 3. The tangential electric field is zero 4. The normal electric field is zero Which of the above statements are correct?
Given is the procedure for construction of flow net. Which of the following options is correct sequence of construction? 1. Sketch one flow line or one equipotential line adjacent to a boundary flow line or a boundary equipotential line. 2. Draw the hydraulic structure, the head water elevation and the soil profiles to a convenient scale. 3. Expand the sketching to more equipotential lines and flow lines, always keeping in mind that roughly square figures should result in the process 4. Establish the boundary conditions.
