Batteries

Connecting is simple. The main issue is what kind of motor do you have? Batteries are DC. Therefore the motor must be DC or a universal motor, or a permanent magnet DC motor. The motor voltage and current requirements must match the battery's voltage and ampere-hour rating. A standard DC motor has 4 leads

A universal motor has 2 leads

A permanent magnet DC motor has 2 leads. The motors with 2 leads are easy: + and --

The 4 lead motor: 2 leads are "field" (F1 F2) 2 leads are armature (A1 A2)

one of each goes to + (F1 A1)

one of each goes to -- (F2 A2)

The motor must be very small in horsepower to work off a battery. There are other more complex DC motors with more leads than 4, but there are NOT going to run on a battery.

Depending on the type of engine, piston, turbine, external, rotary, among others there are numerous components to an engine without which the engine will not function. For example a typical piston cylinder engine(from any car) will not work without any of the following components-piston, carburetor/fuel injection, con-rod, crankshaft, inlet/exhaust valves, camshaft, camchain/timing belt.

An engine is a complex device that requires many finely balanced components to work in harmony. But to pick the most important, it would probably be the crankshaft which is present in any type of engine in some shape or form.

Telephone batteries commonly get hot because they are a form of lithium batteries. All batteries contain chemical reactions within them that produce some amount of heat, it is just that lithium batteries produce great amounts of it.

When a lead-acid battery is discharged, the electrolyte (sulfuric acid) and the active material on the plates of the battery (lead) are consumed to produce water and lead sulfate and current flow. The chemical equation for a lead-acid battery during discharge is: PbO2 Pb 2H2SO4 -->PbSO4 2H2O +Electrical energy. The chemical equation for a lead-acid battery during charge is the reverse with lead, sulfuric acid, and heat being yielded as well as some Hydrogen gas. Ideally, all of the lead sulfate is recombined with the hydrogen from the water to replenish the sulfuric acid. When a lead-acid battery is charged, electrical energy is added to the battery, causing the water and lead sulfate to be recombined to produce electrolyte and the active plate material. During normal charging, hydrogen gas is given off, however if internal damage to the plates or low electrolyte levels exist, internal gassing may create hydrogen sulfide gas. In sealed batteries this would normally not vent to the outside.

A typical D battery has a power output of around 1.5 volts. The power output can vary slightly depending on the specific brand and type of battery.

Depending on the circumstances and previous convictions, battery can be both a misdemeanor and a felony.

Battery on a Police Officer is most always a felony. Simple Battery, is generally a high grade misdemeanor. If you've been convicted of battery once before, it could be upgraded to a low class felony.

Check your states' statues regarding Battery or Assault (though they are technically different, some states fade the meaning).

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.

L6 on a Kidde Carbon Monoxide Detector typically indicates a low battery level. It is recommended to replace the batteries promptly to ensure the detector functions properly. If replacing the batteries doesn't resolve the issue, consult the user manual or contact Kidde customer support for further assistance.

My understanding is 5.7volts is what your supposed to be charging 4 AA rechargeables ,wired in series, with...

Due to loss of current through connectors and wires.. But i cant remember exactly what the voltage needed after the loss is? anyway.. hope that helps you a little

It is not recommended to use a 12 volt 1200mah charger to charge a 9.6 volt Ni-MH 3500mah battery pack as the voltage and current ratings are different. Using a charger with a higher voltage may damage the battery pack and pose a safety risk. It is important to match the charger voltage and current ratings to the specifications of the battery pack.

mA stands for milliampere and it is a unit of measurement used to quantify the amount of electrical current flowing in a circuit. In the context of chargers, mA typically refers to the charging speed or current output of the charger, with higher mA values indicating a faster charging rate.

There is no direct answer for this question, as voltage and wattage measure different quantities. It's kind of like asking "how many gallons are in a foot?" Volts are a unit used to measure the electric potential between points, while watts are a measure of power consumed by a circuit.

They are related, though, as expressed by the power equation: P = V x I

where: * P is power in watts * V is the voltage across a circuit, in volts * I is the current flowing through the circuit, in amperes (amps) Thus, if a circuit has 1 volt across it, and one ampere flows through the circuit, then 1 watt of power is being used. The amount of current depends on how resistant the circuit is to the flow of electricity, and the voltage applied, according to Ohms Law: I = E / R

where R is the resistance of a circuit in Ohms A useful analogy is to compare a circuit to a plumbing system. Let's say we apply water pressure to one end of a pipe, with a closed valve in the middle. The difference in pressure accross the valve is equivalent to voltage accross a circuit. However, with the valve closed, no water is flowing - just as no current would flow through a switch if it is turned off, and thus no wattage would be used. Opening the valve would cause water to flow through a pipe, just as turning the switch on (closing the circuit) would allow current to flow through the circuit. The current flowing through the circuit (or speed of water through the pipe) would depend on the resistance of the circuit (or the diameter of the pipe) and the voltage accross the circuit (the water pressure). The wattage used by the circuit would then be roughly equivalent to the amount of water passing through the pipe per second.

Any strength of power source can be used to make an electromagnet. A single AA battery, used well, can (at least briefly) power an electromagnet that can hold several pounds of metal in the air. An electromagnet's strength is determined by three factors: * the material in the core (air makes a weak magnet; iron a reasonably strong one) * the amount of current in the wire * the number of turns that the wire makes around the core The strength of an electromagnet is often referred to in "amp-turns": the number of turns times the amount of current it has. A simple battery approximates a voltage source: that AA battery pushes out about 1.5V of electricity. Divide that 1.5V by the resistance of the wire (longer wire higher resistance) and you get the current in the wire. At least, until your voltage source gives up and can't deliver that much current any more--then you need a new battery. :)

No, the Black and Decker 18-volt cordless hedge trimmer NHT518 is not designed to operate on a 24-volt battery. Using a higher voltage battery than what the tool is designed for can damage the trimmer and may pose safety hazards. Stick to the recommended voltage for optimal performance and safety.

For the power to flow from your batteries to the device they are supposed to power there needs to be good connections at the battery terminals. With disposable batteries you were guaranteed new terminals each and every time you changed batteries so there was little need to clean the terminals, but with more and more people nowadays powering their GPS receivers and other devices with re-chargeable batteries it's becoming more important to clean the terminals on the batteries regularly. There are a number of ways you can do this. You can use one of the myriad terminal cleaners that you can find in camera or electrical shops. The gadget to look for is the one that looks like a pen but actually has a fiberglass tip, this I find is the best battery cleaner around. Failing that, you can take some fine sandpaper to the terminals - it works just as well (if not a bit too well - don't go overboard on cleaning!). As a rule I give the terminals a clean before re-charging the battery - this way the battery gets a good charge (muck on the terminals affects charging too) and they are then ready for immediate use.

purchase this unit and took it to orlando,florida the next day.....very easy to learn to use. very reliable. spent 10 days with this gps and never missed a show, dinner or intersection to turn.....unit will quickly re-route you if you miss a turn.....very much appove and enjoy this gps unit. Yep.. see my site www.butkus.org/initial/ Yes, I have one. So far it works well. The user guide is nearly useless but the system functions fine. The display is easily visible day or night. The MP3 Player also plays wma files. Navigation is easy and works as well as any other computer navigation system.
If you want a GPS unit that simple takes you to your destination, here ya go. It doesn't take pictures or play videos or give you moon phases - it just tells you how to get someplace. The larger screen is nice but the fonts used for street names can be a little hard to read. The Initial uses the same NAVTEQ data as the name brands so the directional performance should be the same. But as has been said, getting an update is unlikely.. Good basic large screen unit for the money.

You can make a magnet three ways:No1. Get a metal rod and wrap some Insulated copper wire around it. You can use some other wires but it might not work as well. Make sure the wire isn't too thick. Wrap the wire 50+ times. Connect the two ends of the wire to a battery. Don't connect it to a strong power source as it will get very hot. I connected mine to a 1.5 volt battery and it could lift up my scissors then drop them again.(Note: The iron rod now has become a weak permanent magnet. The more current you add to it the more stronger it will be and the longer you have the battery on the stronger it will be.. Also, don't drop it as it will lose it's magnetic properties.)No2. Get a magnet. The stronger the better. Rub one end only of the magnet up a piece of metal then when you get to the end take the magnet off the metal and take it back to the start making sure the magnet doesn't touch the metal. I don't really like this method as it takes a long time to get the metal to pick up anything decent.No3. Get a magnet and let it stick to a piece of metal. The piece of metal will be weak but enough to make the needle on a compass move.

Hard-wired "home" type smoke detectors can not be adjusted for sensitivity. Detectors that appear "too" sensitive are usually very dirty or located in the wrong place. Carefully review the lengthy instructions that come with each detector with regard to selecting a location. Avoid: high air velocity areas such as near air conditioner vents, areas outside bathroom doors where steam vapors waft out, kitchen areas where the cooking smoke can get to the detector before disapaiting Studio apartments pose an obvious problem. You can try cleaning the detector to make it less sensitive by following the manufacturer's cleaning instructions, but when in doubt, replace it. Isn't your life worth $10.00?

outside temp has nothing to do with engine temp, you just have to leave it running for a little bit. i would suggest at least 5 min. Bad thermostat. Probabl;y stuck wide open. or it is heating up, but your coolant temp sensor is bad and it is saying it is cold

Exit signs in public, commercial and industrial locations must have a back-up means of remaining illuminated should the power fail. Most signs meet this requirement with a back-up power supply, such as a battery.

.

There are special exit signs that use phosphorescence (photoluminescent) material (glow in the dark) that remains illuminated for a short time after a power failure.

Also, some occupancies are not required to have "emergency lighting", perhaps because they are small enough to safely evacuate without lights, and exit signs in such an occupancy are not required to have any backup power at all.

.

So, technically, no, not all exit signs are required to have a battery backup. You might want to consult NFPA 101 "Life safety Code" at the library for all the details on exit sign lighting, as well as exit illumination. NFPA 101: 7.10.4, for example, any required emergency lighting must to last for at least 90 minutes, and it must illuminate the exit signs that are not photoluminescent, but not every occupancy requires emergency lighting, let alone backup, or lighted exit signs.

A survey battery test is a collection of related survey questions or assessments that are designed to measure various aspects of an individual's skills, abilities, attitudes, or characteristics. These tests are often used in research, education, or psychology to gather data and insights on specific topics.

When placing voltage sources in parallel, the total voltage is the same as the individual battery's voltages. For example: If I was to place 4 "AA" 1.5 volt batteries in parallel with a life of x hours, the out put would be 1.5 volts with a life of 4x hours.

note: never place batteries in parallel that are not in the same condition (charge, voltage, ect...).

Galvanic cell, voltaic cell, electrochemical cell. Do not confuse it with electrolytic cell.

The voltage of 6 AA batteries connected in series is 9 volts. Each AA battery typically provides 1.5 volts, so when connected in series, their voltages add up.
