Question 1: The electric potential is constant throughout a given region of space. Is the electric field zero or non-zero in this region? Explain.
ANSWER
When the electric potential is constant through a certain region of space the electric field is also zero in this region.
Explanation
The electric field intensity depends upon the rate of change of potential with distance.

When the electric potential is constant ΔV= V2 – V1 = 0, hence the above equation becomes,

Therefore, electric intensity is zero when the electric potential is constant.
