Batteries

No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.

To maintain the 12 volts using four batteries they have to be wired in parallel connections. This means that all of the positive posts are connected together and all of the negative posts are connected together. The total sum of all of the batteries will equal 12 volts.

If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.

motorcyclemessiah ON BEHALF OF THE JUNKIES AGAINST CRIME LIBERATION FRONT says what i would guess at to arrive at h3po2 is if you started with 200 grams of sodium bi phosphate 140 ml HCL+140 ml H2O gently heat till sodiun chloride precipitates out of solution then test with hydrometer it should come up at 11.25 specific densityand it should be able to be burnt giving of a good flame and leaving a black residue if this dosent work it is used in the dairy pig and electroplating industrys so drop the power to the place and bolt cutter the locks and send us the lot and we will give you some speed when we make it regards the motorcycle messiah.

If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.

Yes, you can use a 2Amp car battery charger on a 12 volt sealed, leak-proof battery. However, be mindful of properly setting the charging voltage and current output to prevent overcharging or damaging the battery. It's recommended to refer to the manufacturer's instructions for the appropriate charging specifications for your specific battery.

Radiation-feeding bacteria like Deinococcus radiodurans can withstand high levels of radiation but cannot completely eliminate it. Instead, they can repair their DNA more effectively than other organisms, making them useful in certain applications like bioremediation of radioactive waste.

Like lithium ion batteries, they do not suffer from battery memory but are also effected by gradual capacity loss caused by oxidization. It happens over a span of years from the manufacturing date, and lithium polymers (lipos) are basically lithium ion batteries that are easier to mold into various shapes needed for certain applications.

Yes, a AA battery typically provides 1.5 volts, so you would need to connect multiple AA batteries in series to reach 12 volts. For example, connecting eight AA batteries in series would provide a total of 12 volts.

It is not recommended to use a battery with higher amperage than what is specified in the manual, as it can overload the electrical system of the bike. It's best to consult with a mechanic or specialist to determine the appropriate battery for your specific needs. Alternatively, you could consider adding a separate auxiliary battery for your additional electrical components.

No, a battery does not represent a system at equilibrium. A battery operates by creating a potential difference between its terminals through chemical reactions, which is a non-equilibrium process as it involves the flow of electrons from one terminal to the other.

Nothing would happen, the flashlight simply wouldn't work. Switch the batteries back around and it will work.

This is purely because the contacts don't line up properly. A normal incandescent lamp will work either way round. A modern LED flashlight however is polarity sensitive.

Yes. Exactly the same way, and described by the exact same math, as the change

in the gravitational force between masses as the distance between them changes.

750 mAh refers to the battery capacity measurement of 750 milliampere-hours. It represents the amount of energy the battery can store and deliver over time. In practical terms, a higher mAh rating typically means the battery can power a device for a longer period before needing to be recharged.

A car battery is typically a lead-acid battery, which is designed to provide high bursts of power to start the engine and also power the vehicle's electrical systems.

Yes, a 12 volt 1 amp battery charger can recharge a 12 volt 180 Ah battery, but it will take a significantly long time due to the low charging current. It is recommended to use a charger with higher amperage for faster and more efficient charging.

Battery powered 3D glasses means they are active 3D glasses and they only work with their own manufactured brand. However the compatibility of passive 3D glasses for other TVs are much higher. They work on any 3D TVs or theaters if they use the same passive technology. The passive 3D TV glasses are also lightweight due to no batteries being attatched. Plus, they don't need to be charged everytime before/after use unlike the active ones.

This might not be a really good answer but you could use one to power a flashlight in a storm when you cant find batteries I guess. Haha. Something along those lines would be the real world application. Is this for science fair?

Remove the four screws that hold the back on.remove the cover,inside there should be a gold cover through which you can see the battery.At one end there is what looks like a hinge this is in fact the release used a tiny flat screw driver in the center slot to release it.Then the battery can be removed and a new one can be put in.Then click the release back in place to hold the battery in and then screw the back on job done.

Most washing machines use a power cord to connect to an electrical outlet for power, rather than batteries. However, some modern washing machines may use small internal backup batteries to retain memory settings in case of a power outage.

when a battery is charged the electrons are received by the acidic compound in the battery. then it is stored in battery. then released to anything you wanted.

"if you think this won't work buy a new battery instead of asking such question in web"

ya. we are using diode in a battery charger to convert ac into dc. 230v dc is step down by using step down transformer

To have a disadvantage you need to have a set of criteria for evaluation. There is no inherent disadvantage. Batteries in parallel have the same voltage as a single battery, but can deliver more current.

If you put the batteries in a flashlight in the wrong direction, the electrical current won't flow properly, preventing the flashlight from turning on. It's important to insert the batteries according to the correct polarity indicated on the device to ensure it functions correctly.

Sure you can. But consider what could happen if you did. If precision of time or speed was built into this 6-volt system, a 12-volt battery will make it work faster until something shorts or burns out.

If you need more lasting power for the 6 volt system, you should consider putting two 6-volt batteries in parallel to power your 6-volt system.
