Do the electric field lines point in the direction of increasing or decreasing potential?
Electric field lines always point in the direction of decreasing electric potential. A system consisting of a positive charge and an electric field loses electric potential energy when the charge moves in the direction of the field (downhill).
Why do electric field lines move from high to low potential?
A positive charge, if free to move in an electric field, will move from a high potential point to a low potential point. Again, note that the work done by the electric field is positive, and the negative charge will lose electric potential energy and gain kinetic energy as it moves against the field.
Does the electric potential increase or decrease along an electric lines of force?
Along the electric line of force, electric potential decreases.
Which point is at the higher potential?
The higher potential is the point of higher concentration of charges and lower potential is the point with a lesser concentration of charges. Historically scientists believed that the positive charge is the one that flows.
Why electric potential in a field of negative charge is lower at near points and higher at distant points?
The negative value for voltage means a positive charge would be attracted from a larger distance, since the potential is lower (more negative) than at larger distances. Conversely, a negative charge would be repelled, as expected.
Will the electric field always be zero at any point where the electric potential is zero?
(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. … At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.
