The direction of the electric field is the direction in which a positive charge would move if placed in the field. This is also known as the direction of the force on a positive charge in the field.
The direction of the electric field can be determined by the direction of the electric field lines. These lines always point in the direction of the field at any given point.
No, the direction of the electric field can vary depending on the location and arrangement of charges. It can also change over time if the charges are moving.
Yes, the direction of the electric field can be zero at certain points in space where the field is cancelled out by equal and opposite charges. This is known as an electric field null point.
The direction of the electric field determines the direction of the force on a charged particle, which in turn affects its motion. A positive charge will accelerate in the direction of the electric field, while a negative charge will accelerate in the opposite direction.
