To graphically represent the
electric field we use the concept of lines of
force: lines which are tangent at each point to the field
intensity vector at this point. The visual shows us their
characteristics. Study what the field created by a positive charge, by
a negative charge and by pairs of charges of equal or different values,
is like. For each case draw at least 6 lines of force. Don't forget to
click on the init control. |
