If the electric field is in the plane of coil the it's value would be E= a/2r×(dB/dt)
Any charge placed in this reason will move perpendicular to magnetic field in a circular orbit.
It's can be find as ∫E.dl = dΦ/dt
 E.2pi×r =pi×a^2× dB/dt (as Φ=BA).

  Earthing provides a safety measure for electrical circuits and appliances. A thick metal plate is buried deep into the earth and thick wires are drawn from this plate; these are used in buildings for the purpose of earthing near the mains supply. Why only "thick" wire and "thick" metal plates are used?

Sir the ans to this quesn is i3=-5/6 A so this means curretn flows from A to D (opp to current indicated in diagram) but through KVL we found PE at D is always greater than A, C,E hence it will always flow from D to other points. 1) How it is voilating Ienter=Iexit. 2)How current flows from A to D even though D is high PE?
