How many volts does an AA battery deliver?
485757
AA battery is typically rated as 1.5V\n\nIn reality, it may vary from 1.6V (new) to 0.9V (dead) in its life span.

The voltage across each resistor will be 12 volts as each is effectively directly connected to the battery.\nIt is the current flow through the resistors which will be different.\nVolts/Ohms =Amps - that is\n12/7 amps or 12/5 amps now get your calculator out!\nRoyS

It doesn't really have one. Its just a useful way of characterising the battery's behaviour.\n\nBatteries approximate to perfect voltage sources - in other words, the voltage across them does not drop no matter how much current you draw. (By contrast, solar cells approximate to perfect current sources).\n\nOf course, in reality the voltage does drop a little, and drops more the more current is drawn. The relationship is almost a straight line for small currents, and so it is useful to know the rate the voltage drops as the current increases, or dV/dI. Now of course the units of volts/amps is ohms.\n\nWhere this relationship is linear (small currents) you can also usefully include the internal resistance as a fictitious resitance in a circuit - it will do just as well as accounting for the change in voltage (can you see why?).

That would depend on the voltage. Current = Watts / Volts\nA couple of examples:\n110V - 90.9 Amps\n220V - 45.45 Amps\n240V - 41.67 Amps\n440V - 22.7 Amps\n10,000V - 1 Amp

the single solar cells you can buy at Radio Shack are about .5 volts each so I imagine a calcutor solar cell would be anywhere from .5 to 1.5 volts

Battery capacity is usually measured in mA H. e.g a 100mAH will delivery 100mA for 1 hour or 10mA for 10 hours (at the rated voltage)\n\nBigger batteries tend to have a larger capacity - i.e. bigger mAH figure

You would wire them in parallel so that the voltage would be the same across each of them, because in parallel the amperage increases, not the voltage.  If you were to wire them in series, then the voltage would add to 48 volts, which would destroy your electrical system.  You would likely need a better alternator to handle the charging of all of these batteries, too but I'm not sure on the specs of an alternator that you'd need.

5 x 1.5V is???\n\n\n7.5V DC

google it??  I dont think there are any, a 9v battery is not strong enough to be fatal by itself.  actually, maybe i was wrong thinking that, if the darwin awards can be believed.

Use ohm's law (I=E/R); 2 AAs are 2.4 to ~3 volts depending on battery type, so 0.4 to 0.5 A.\nHOWEVER, if you measured the bulb's resistance cold, it will be higher when hot, so it will draw less current.

easy,you got to let the charge leak out.when your a car you can take your shoes off and stuff like that but there really is nothing to worry about just because the voltage can range from 10 000 to 20 000 volts it does not necessarily mean its going to harm you, it has a very low current(which does harm in high doses.

You'll need, as the name may suggest, a voltmeter.  Also applicable is a multimeter - which you'd then set to voltmeter mode.\n\nAt which point you'd just put one contact on one one end of the battery, and one on the other, and see what the equipment reads.\n\nMy money's on 1.5V :)

mAh (milliamperes per hour) rating is the measure of how much power is stored in the batteries.  It indicates how long the electric gun will run relative to the (electrical) current draw.. or flow.  \n\nNiCad cells can readily, or easily, give out 10 times its rating.. and still output needed power at 15 times (but it will heat up fast). NiMH cells can only give out around 6-7 times its rated mAh capacity.. straining at 10 times the rating   A stock Tokyo Marui AK47 draws as much as 10,000-12,000mAh.  That's 8-10 fold for a 1200mAh battery, but only 5-6 times the rating for a 2000mAh. It's best to get as high mAh rating as you can get (for the size of the battery pack) or can afford.   Not only does it make for longer running time, it also delivers power better.   Largest readily available for NiCad is 2400mAh, while for NiMH, it's 3600mAh.. both sub-C size.

The info provided is related to current.\n\n23mAh (milli amp hours) x 7.3 (hrs) = .17amps\n\nYou have no Voltage information, please recheck.

The battery voltage is mainly a function of the metals used for anode and cathode. The lemon merely provides the electrolyte through which the metals can exchange ions. The copper-zinc combination typically used for lemon batteries generates a bit less than a volt.

what do you like to do? a dry cell normally is 1.5volts. if you want to make a 4.5 volt supply, connect the negative of one to the positive of the next and also the third. the positive of the first and the negative of the third will give you 4,5 volts. for higer voltage, increase the number of dry cell.
