you will have to get 2 batteries and compare it
No
No. For one thing, you can't recharge just any old 9volt battery; it has to be a specially-designed rechargeable for which there is a specially designed charger. For another, a car battery charger puts out about 13-15 volts.
This depends on the type of battery. Usually, in an AA, AAA, C, etc. The spring side (in the holder) goes towards the flat side (of the battery), and the two bumps go together. If it is a battery with two springs on one side, (a 9volt battery or a D battery, etc.), you look on the battery for the positive and negative markings.
3 ohms. 9 volts across a 3 ohm resistor becomes 9/3 or 3 amps.
No. The person who designed your appliance had a 12v adapter, so when he designed the adapter connector he put a resistor in it to drop the voltage to 9v.
yes any electronic paintball gun needs a battery. If your buying it new it should include a rechargeable 9volt. You can also use just regular 9 volt batteries in a pinch.
It varies from one 9 volt battery model to another. The typical Alkaline 9 volt battery you find in many toys and smoke detectors has 565 mAh (Milliampere Hours) of power. A Zinc Carbon model has 400 mAh. A Lithium has 1200 mAh. There are 1,000 mili amps in 1 amp.
You cannot use either them, for danger of overvolting the battery, which may cause it to explode. Find the correct Nickle-metal hydride battery charger.
There are many different types of batteries: Tiny coin batteries, as in hearing aids, can weigh just 2 to 5 grams AA batteries can weigh from 15 g (lithium) to 31 g (Nickel metal hydride rechargeable). Size D flashlight batteries can weigh from 110 g (lithium) to 175 g (NiMH rechargeable) Wet Cell batteries for cars and boats normally weigh several kilograms.
A classic and ancient experiment is to get a compass, a battery (9volt is fine), and some wire. Notice that the compass changes when the circuit is closed (wire connected to the two terminals). You can also see that the compass gets affected less when it is far from the wire versus next to it. If your interested in the math behind the experiment, you may want to do some research on the Biot-Savart Law. The Biot-Savart law describe the magnetis field when the current is constant, or not time-varying. A more general form of the equation is called Ampere's Law, and the more general case of that is Maxwell's equations.
The gauge inside is telling you how many volts your alternator is putting out, not yoru battery. Go have your alternator tested to see if it is putting out 14 volts or more...........if not, you are drawing more current out of the battery then what the alternator is replacing and you are going to end up with another dead battery. They can test alternators at Autozone for free or you can go get a multi meter and test it yourself. Have the alternator checked.
Zip tie a 9volt to you handlebar.
