- 22-3 Electric Field Lines
- Field lines: useful way to visualize electric field E
- The relation between the electric field lines and electric field vectors:
- At any point, the direction of a straight field line or the direction of the tangent to a curved field line gives the direction of E at that point.
- The field lines are drawn so that the number of lines per unit area, measured in a plane that is perpendicular to the lines, is proportional to the magnitude of E.
- Thus, E is large where field lines are close together and small where they are far apart.
