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.

How many amps does a AAA battery have?

A battery can have Ampere hours, but how many amps it will deliver is influenced by what the battery is hooked up to.

A bulb of resistance 200R is connected to a 9v battery what current is flowing in the circuit?

Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).

9v! More voltage, more strength! Many 9v batteries merely have 1.5Volt cells jammed together to make 9V!

True or false a 9V battery contains 6 times as many free electrons as a 1.5V 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).

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.
