How many amps are in a 9v battery?
Asked in Acids and Bases
What is the difference between the car battery and 9V alkaline battery?
A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.
What is stronger a 1 amp battery charger or a 9v battery?
You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.
A bulb of resistance 200R is connected to a 9v battery what current is flowing in the circuit?

What is stronger 1.5 volt batter or a 9 volt battery?
How many amps in a 9 volt battery?
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).

How do you determine how many amps a battery can handle under continuous conditions?
If you have a 12point6V battery and a 9V receiver how can you work out which resistor is needed?

Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
