Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Item 7
Learning Goal:
To understand the nature of electric fields and how to draw field lines.
Electric field lines are a tool used to visualize electric fields. A field line is
drawn beginning at a positive charge and ending at a negative charge. Field
lines may also appear from the edge of a picture or disappear at the edge of
the picture. Such lines are said to begin or end at infinity. The field lines are
directed so that the electric field at any point is tangent to the field line at
that point.
