The basic theory of 12v battery charger



The basic theory of a 12v battery charger is a tutorial addressed to the people in need how a how to make 12v battery charger at home

we have to know the process in order to make it ,after knowing the basic theory and the working process of a lead acid 12v battery we can build assemble or make a 12 volt battery charger with protection. The 12v battery is still in demand these days altho the lithium battery technology is fighting back, but till 18650 battery will win we still have to use lead-acid battery because there are more affordable at this point.As well as starting the engine, an SLI battery supplies the extra power necessary when the vehicle’s electrical requirements exceed the supply from the charging system. It is also a stabilizer, evening out potentially damaging voltage spikes.[2] While the engine is running, most of the power is provided by the alternator, which includes a voltage regulator to keep the output between 13.5 and 14.5 V.[3] Modern SLI batteries are lead-acid type, using six series-connected cells to provide a nominal 12 volt system (in most passenger vehicles and light trucks), or twelve cells for a 24 volt system in heavy trucks or earth-moving equipment, for example.

How Power Savers Work – Basic Buying Tips

Can you really save 40% on your electricity bills by plugging a small box into your AC socket?

In the past six month a number of products have been advertised on TV and online which seem too good to be true. I’d like to explain the reality of these exciting claims and give you a layman’s understanding of how Power Savers work.

A Power Saver is a device which you plug in to your power socket. Apparently just by keeping the device connected it will immediately reduce your power consumption. Typical claims are savings between 25% and 40%.

The technology behind Power Saver units comes from German research coupled with Asian manufacturing and it is based on sound scientific principles.

Electricity is not stable. When electricity flows the voltage can rise and fall all the time. The rises in voltage are known as ‘spikes’ and they cannot be used by your appliances at all. All these spikes do is waste your electricity. These power spikes also convert electrical energy into heat energy which leaks power from your circuit. Not only that but the heat will also do long-term danage to your wiring and to your appliances.

There are a few Power Saver models on the market but they all work along the same principle. They store the electricity inside of it using a system of capacitors and they release it in a smoother way to normal without the spikes. The systems also automatically remove carbon from the circuit which also encourages a smoother electrical flow. This means that you will have less power spikes. More of the electricity flowing around your circuit can be used to power your appliances than before.

There are many factors which do affect the efficiency of your Power Saver. The device works immediately after plugging it in although it can take as long as 8 days before it has adjusted itself for peak performance. The rate of savings will depend on what kind of appliances you have connected. All appliances are different but expect savings of up to 25% on lights, 30% on air-conditioning units and up to 35% on other appliances.

The highest savings will be in areas where voltage supply is less stable. Locations close to shops, restaurants and light industries tend to gain additional savings from Power Saver devices.

So how can you be sure that your Power Saver is working correctly?

Most often Power Savers come fitted with a light to indicate that it is working. If you have access to an electricity meter then you should see it immediately slowing down. Assuming that the light is on and that you leave the device unattended you can expect savings immediately. Be aware that often electricity companies will not take meter readings each month. Often bills are calculated on monthly averages which self-correct over time so please be aware of that in using your bill as a guide.

Finally, it is highly recommended to order your Power Savers from companies offering 100% guarantees for longer than 30 days. Remember that 30 days may not be sufficient time to truly know if the device is working as effectively as you expect. Try to work with companies that extend their guarantee dates to at least 60 day which gives you a much longer period to assess the benefits.

Electronics and Tips on Building a Basic Electronic Circuit

Electronic components are physical entities within the system. Their sole purpose is to affect the associated fields or the electronic via a desired reliable method with the intended purpose of the electronic system. Some of the usual components are transistors, diodes, resistors, and capacitors.

Digital devices are types of electronic systems that use digital signals. Its representation of Boolean algebra is commonly used in mobile phones, computers and other costumer products. Digital devices and other digital circuits are usually made from large assemblies of logic gates.

Analog devices are electronic systems with a constant variable signal. The earliest device invented the was analog. The major difference between digital and analog electronics is its noise, precision and design difficulties.

The process information is programmable in analog electronics. They are more vulnerable to noise as compared to digital electronics. In digital, as the information is programmed and as the signals stay long inside the range value, digital devices represent identical information similar to analog devices.

Digital electronics are much smaller and easier to design as compared to similar analog electronic processes. This is one of the major reasons why the latter is more common and preferred. An analog device should be designed by hand. The procedure is less automatic as compared to digital.

There are numerous electronic stores around the world. The Correctional Electronic Store is one of the more known. It was built with the intention to support the Correctional Facility Industry or CFI having the quote systems for replacement and spare parts. This is deemed as the major requirement for the maintenance of all fire alarms and security systems that are operational within the facility. The store has a large variety of manufacturers that provide excellence parts, specifically for part replacements and system maintenance.

Dick Smith Electronic is the largest online retailer of Entertainment, Electronic, Communication and Computer products in Australia. Its online store provides consumers with not only exceptional ranges of products but also unbeatable after-retailing support and first class service. The leading products of the store include Yamaha, Sharp, Philips, Panasonic and Samsung as well as Sanyo, Canons and so much more. Dick Smith Electronic has several headquarters, particularly in New South Wales, South Australia and Western Australia. They also have stores in Victoria, Queensland, Tasmania and the Northern Territory of Australia.

E-commerce Carts Electronic store provide low priced web services, giving you a fully designed or professional e-commerce website without the need to know the code. The store also provides easy to use website solutions, making it easier for online businesses to work on the Internet. E-commerce Carts Electronic Store is the leading provider of Linux web hosting, windows, web design and e-commerce shopping carts.

You can build an electronic circuit yourself also. It is quite easy. First buy some load. The simplest load can be used in a basic circuit. This would include an motor and lamp as well as a buzzer. Find some low-power components from several stores like RadioShack.

Buy a battery and power supply. For electronic circuits, the power supply should be as close as possible to the electrical energy of the components, without the need to leave over. You can purchase everything you need.

Connect one of the batter terminals to the button or switch. You can only do this by holding the uncoated end of one of the wires. Then, finish wiring of the circuit and place the batteries. Connect some load terminals to the free terminal of the holder of the battery.
