Independent of Path?

• This is the definition for the potential difference: DVAB=VB - VA.

• The integral is the sum of the tangential (to the path) component of the electric field along a path from A to B.

• The question now is: Does this integral depend upon the exact path chosen to move from A to B?

• If it does, we have a lousy definition.
  • Hopefully, it doesn’t.
  • It doesn’t. But, don’t take our word, see appendix and following example.
