3$\begingroup$ Do you mean a violation of energy conservation? The phrase "a violation of energy" doesn't really mean anything. Furthermore, the reason that equipotential contours cannot intersect has nothing to do with energy conservation, really. Did somebody say that it did? Or did they just say that equipotential contours cannot intersect, and you assumed it was due to energy conservation? I'd be happy to make a real answer once your question is more clear. $\endgroup$– Colin KCommented Jan 4, 2012 at 2:02

$\begingroup$ Yes I do mean conservation of energy. I apologize for being vague. I was watching a video by Walter lewin and he commented this. $\endgroup$– LemonCommented Jan 4, 2012 at 4:57

$\begingroup$ the simple fact is that since its is an equipotential line, the intersecting point will have +5 as well as -5 volts!!! how can that happen?? $\endgroup$– Vineet MenonCommented Jan 5, 2012 at 5:21

$\begingroup$ "Why can't +5 = −5?" $\endgroup$– endolithCommented Jan 5, 2012 at 21:26

- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>
[example](https://example.com)
<a href="https://example.com">example</a> - MathJax equations

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. quantum-mechanics), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
