Talk:Ampere-hour
From Wikipedia, the free encyclopedia
It says here E=CV, though I doubt this is the case. C is commonly used for capaciTANCE (a different yet extremely common parameter in electricity) while Q is used for charge. While it's possible in the same circles where mAh are used, (rather than Coulombs) C is used for capacity, I doubt this.
[edit] E=QV
Variables should not have an associated unit of measurement. Those equations should be correct *despite* ones use of units (as long as the units are properly tracked). Fresheneesz 02:11, 12 August 2006 (UTC)
[edit] Battery description
All the stuff about batteries should be moved to the battery (electricity) article. Articles about a unit of measure should not be dominated by one use of that unit. --Wtshymanski 22:34, 17 November 2006 (UTC)

- sorry, I don't agree, I've just been looking this unit of mesurament up in regard to batteries details and that info has been very useful to me. —The preceding unsigned comment was added by 192.33.238.6 (talk) 15:30, 5 April 2007 (UTC).
[edit] Am I missing something?
[...] a CD player draws a constant current of 200mA from two rechargeable AA batteries that have a capacity of 2300mAh each. So, 2.300Ah / 0.200A = approximately 11.5 Hours of battery life.
I am not well versed on electricity, but if we are talking about 2 batteries with a capacity of 2300mAh each, wouldn't that bring the total amount of capacity to 4600mAh? The CD Player on that example would then last 23 hours... --CronoT 15:31, 20 December 2006 (UTC)
- The batteries are connected in series, giving a total voltage of 3 V with a capacity of 2300 mAh. The same current flows through both batteries. Would they be connected in parallel, the voltage would be 1,5 V, with a total capacity of 4600 mAh. LHOON 15:39, 20 December 2006 (UTC)

- Heh, that was fast! :-) Thanks for the clarification. Maybe this should be clarified on the article as well, for the sake of newbies like me. --CronoT 16:56, 20 December 2006 (UTC)
