Frequently Asked Questions

What direction do electric field lines go?

Electric field lines point in the direction in which a positive test charge would respond to the electrostatic force; that is, away from positive charges and towards negative charges.

How is the direction of the electric field defined?

The direction of an electric field is defined as the direction in which the electric force would be felt by an object with a positive charge placed in the field. Thus, the field would point away from a positive charge and toward a negative charge, since like charges repel and unlike charges attract.

What direction is required for the electric field?

Electric Field. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

How can electric field lines be directed?

Electric field lines always start from positive charges and end at the negative charges. They don't form closed loops. If an isolated charge is present, the electric field lines are directed radially from the charge (inward if q<0 or outward if q>0).
