SUMMARY
The discussion clarifies that when the electric field (E-field) is zero in a region of space, the electric potential (V) remains constant rather than zero. This is derived from the relationship V = -∫ E dl, where if E = 0, the integral does not yield a specific value but indicates that potential can vary by a constant amount. The relationship E = -∇φ shows that the electric field is the gradient of the potential, and any constant shift in φ does not affect the electric field. Therefore, the potential can be any constant value, not necessarily zero.
