Could someone give me a word definition of Ampere's Law as I have googled some definitions and they all seem a bit confusing. Thanks :)

Tell us what you know, what you have understood, and what exactly you didn't. Zz.

Try https://www.iit.edu/arc/workshops/pdfs/Amperes_law.pdf
Or http://www.maxwellsequations.com/am...mpereslaw.php Ask again if these are not clear enough; personally I prefer the mathematical definitions  they are what I would actually use.

Ampere's Law
For any current geometry that produces a magnetic field that does not change in time,
[itex]\Sigma B_{}\Delta l = \mu_{0} I[/itex] Where [itex] \Delta l[/itex] is a small segment of length along a closed path of arbitrary shape around the current, [itex]B_{}[/itex] is the component of the magnetic field parallel to [itex] \Delta l[/itex], I is the net current passing through the surface bounded by the path, and [itex]\mu_{0}[/itex] is the permeability of free space. The sum of all these must be taken around the closed path. Personally, I find the best way to understand is to do.

UltrafastPED, BOAS: aren't you at all curious to figure out first at what level the OP could comprehend?

Will try to use this approach on any further questions I feel capable of assisting with.

Thank you everyone. I am revising for an exam and i think i was just overloaded with the different ways of defining Ampere's Law on google and I just wanted the easiest way to state it as well as a way to best comprehend it. I have found all of your answers helpful and BOAS I now know for sure what each notation means. UltrafastPED thank you, those links are a great help and ZapperZ thank you for your concern to help me in the best way possible. I am sorted now, thanks guys :)
