V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.

What is meant by a cell has a voltage of 1.5volt?
No. The potential DIFFERENCE of a battery (or, more accurately, a dry cell) is 1.5 V.
A battery has emf of 6 v and an internal resistance of 4 ohm it is connected to a 2.6 ohm resistor a switch when switch is open the potential difference between the terminals of a battery is?
6 volts
A bulb is connected to a battery having a potential difference of 6 V A voltmeter is connected across the bulb What is the reading on the voltmeter when the bulb burns out?
Assuming you're referring to a simple incandescent bulb . . .When the bulb burns out, the filament is open, and it is electrically no longer there.The voltmeter is then across the battery, which is open circuited, i.e. without a load.The meter measures the open-circuit voltage of the battery, nominally 6 V.
A torch is operated by a 3v battery when the switch is closed the bulb draws 0.075 amps from the battery what is the resistance of the bulb?
V=IR R=V/I V=3V I=0.075A R=3/0.075 = 40 ohms
What is the unit of potential difference?
The unit for electric potential difference is the volt (V).
Is 4800mAh is equivalent to 56 Wh?
Only if the battery is rated at 11.66V. mAh / 1000 => Ah (4800 mAh = 4.8 Ah) Ah * V => Wh (4.8 Ah * 11.66 V = 55.97 Wh)
Do you need 3 x12v 12 ah batteries to make a 36v 12 ah battery or do you use 3x 12v 4ah batteries?
The first choice was the best: 3 x 12 v 12 Ah will give a 36 v 12 Ah battery. In series the same current goes through all the batteries so the Ah capacity does not change.
What size battery does a 2004 Subaru Outback take?
75d23l (12 v - 52 ah).....
What is the specification of the battery on a 2003 Acura TL-S?
12 v 65 ah/20 hr
What is the difference between a 2.4 v and a 3.6 v cordless phone battery?
The 2.4 v battery doesn't have as many volts so the phone has less battery time, so you need to charge it more often, than the 3.6 v battery. Hope I helped you!
What is the maximum energy delivered per second from a 12 V 4 Ah car battery?
That depends on the characteristics of the battery. The numbers you quote don't give enough information. 4 Ah is simply a measure of the battery's total energy storage (for rexample, 1 ampere during 4 hours, at the specified voltage), not of how fast it can be released.
What is the potential difference that is generated by a battery with a 1.5 V cell in series with a 2.0 V cell?
3.5v You add the voltages when placed in series.
Can you use a plug adaptor with battery charger?
If you're using the same input voltage, as the battery charger was designed for, then a simple socket adapter will make absolutely no difference to it's function. On the other hand, using a different input voltage to that which the battery charger was designed for, will make a considerable difference to the output voltage and current. Hence a 120 V automotive battery charger, if plugged into a 220 V socket will deliver nearly 24 V to a battery instead of 12 V, although the current supplied will be half it's normal value.
What is meant by a cell has a voltage of 1.5volt?
No. The potential DIFFERENCE of a battery (or, more accurately, a dry cell) is 1.5 V.
When a 12 V battery ie a battery of EMF 12 V is connected across a lamp with a resistance of 6.8 ohms the potential difference across the lamp is 10.2 V Find the current through the lamp?
The idea is to use Ohm's Law (V=IR). In this case, the relevant voltage is the 10.2 V across the lamp.
What is the maximum energy delivered per second from a 12 V 4 Ah car battery in joule?
Energy = 4Ah x 3600 seconds x 12 volts = 172,800 Joules
How do you say grandmother and grandfather in portuguese?
Grandmother is "avó" and grandfather is "avô" in Portuguese.
