The question should be how many amp-hours in a battery. In a small batt. like a 9V, this is measured in milli-amp hours (mAh), with 0.5 amp hours equaling 500 mAh. This means the battery could power a 0.5 amp load for 1 hour. Data I have seen shows the best alkaline 9V being between .3 and .5 amp-hour (300 to 500 mAh).

Depends on what you connect to it. If it is a resistor (R) you will get a current of 9/R amps. If capacitors and/or inductors are involved you will get various transient effects depending on what circuitry you use. A short circuit will give many amps for a very short period.

Can you use a 9.6 volt DC drill battery to extend the life of a standard 9 volt DC electronic item?
no, a 9 volt battery is small (goes in a smoke detector) a 9.6 volt battery is much larger, and it is not a DC battery (direct current) but NiCd (nickel cadmium.) two totally different things.
What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
Current will go up by a factor of 6 times in that scenario.
Does a 9 volt battery have more energy than a 1.5 volt battery?
A D cell battery has a voltage output of 1.5 volts, while a 9 volt battery produces about 9 volts. This is just the potential energy though. D cells provide far more current for a longer time then a 9 volt battery. In terms of overall power output, a D cell in give you many times more power than a 9 volt battery. Physical size, in this case is a good indicator as the material inside is the same.
Does a 9 volt battery light a light bulb?
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
What is stronger 1.5 volt batter or a 9 volt battery?
9v! More voltage, more strength! Many 9v batteries merely have 1.5Volt cells jammed together to make 9V!
How much power is generated when a 9 volt battery produces a current of 5 amps?
45 Watts
Can you use a 3 volt charger for a 9 volt battery?
No
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
What Happens if a 9 volt battery touches another 9 volt battery?
It heats up very hot and may explode.
Can a 9 volt charger be used to charge a 7.2 volt battery?
no
How fat is a 9 volt battery?
1.3cm
Where can you find dcs?
a 9 volt battery
How do you reboot a rechargeable 9 Volt battery?
buy a battery charger
What does a battery clip do?
it operates a battery,mostly a 9 volt battery
What is the difference between a 9 volt battery riding car and a 12 volt battery car?
One is 9 volts and the other is 12 volts. They do not interchange!
Where can someone find science projects to do with a 9 Volt battery?
There are many science projects one might do with a 9 volt battery. The official Energy Quest website has some great ideas that a science student may enjoy.
