LINE INTEGRAL OF ®E
The line integral of electric fields is defined as the integral
A∫B ®E. ®de
The value of line integral depends only on the position of points A and B, and is independent of the
path between A and B
A∫B ®E. ®de = - B∫A ®E. ®de
Line integral for a closed path is zero . Æ ®E. ®de = 0
(such electric fields are called conservative fields).
Note : There exists one more type of electric field, called induced electric field. It is non-conservative
for which . Æ ®E. ®de = 0
