Explain battery eliminator,its working,circuit diagram and uses and constructing simple battery eliminator?

A battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a DC voltage that may be used by a second device originally designed to be powered by batteries.\n\nA battery eliminator does away with the need to replace batteries but may remove the advantage of portability. A battery eliminator is also effective in replacing obsolete battery designs.\n\nFor circuit diagram and working visit this link:\nhttp://homepages.which.net/~paul.hills/Emc/BecBody.html

There's a great article explaining thyristor operation and showing basic circuit diagrams here: http://www.ibiblio.org/obp/electricCircuits/Semi/SEMI_7.html\n\nThere was also a very good reference book called "SCR Manual Including Triacs and Other Thyristors" published by GE from the early 1960's into the late 1970's.  It's a highly prized source for many engineers, and you -may- be able to find one for sale, if you're lucky. (No, you can't have mine :-P )\n\nDo a Yahoo! search for "thyristor circuit diagram" and you'll get thousands of results. :)

Emergency Light has electrical energy storage device called battery, charger unit, lamp and switching circuit. When power is available it is used for charging Battery. When power goes OFF, supply from storage Battery to lamp is switched ON by switching circuit and lamp glows. When Power supply is restored, switching circuit disconnects supply from Battery to lamp. Switching circuit gets its initiation command from status of normal supply (absence or availability of normal supply)

frequency generator is like tank circuit(lc circuit). it's main function is to regulate the energy stored in the inductance and capacitance. to know more you can read RESNICK HALLIDAY WALKER

Different chemical species are connected by some means that allows ions to flow between them, but does not allow them to mix.   The different chemical species are chosen so that one of them undergoes oxidation, or loss of electrons, while the other undergoes reduction, or gain of electrons.\n\nWires connect to each of the chemical species and to positive and negative terminals of the battery.  When they are used, electrons flow into the wire from the oxidizing side, through the circuit and return to the reducing side.\n\nA simple cell that shows this flow can be made from a lemon and two different pieces of metal (like a copper wire and a length of solder).  Just push the pieces of metal into the lemon and you can measure a voltage from one wire to another.\n\nCommercial batteries are a bit more complex in construction.

You should remove the batteries because even if they are not used, the chemicals in the battery can eat through the housing and damage the device.\n\nAlso, the chemicals in the batteries have a "shelf-life" where they will react slowly even if there is no electrical discharge.

Your question is not clear at all, but let me guess a little.\n\nAre you asking for the function of each component in the circuit ???\n\nIf so, light bulb will be the load.\nConductor is the mean for the current to flow.\nswitch, is for closing or opening the circuit\ninsulation, to keep conductors to short the circuit.\nmeter, to measure the voltage or current or power being used at some time.\nbattery is the power source to get the circuit to work.\n\nNow I guess I earn 10 points for best and only answer.

2 electrodes and a battery

Batteries use the different potential that certain chemicals have. Battery consists of 2 chemicals which potential different are significantly enough to generate voltage difference. Reaction happening in a battery is redox (reduction-oxidation) which allows electron transfer. Positive terminal of the cell has the higher potential.\n\nAs the reactant are all used up, reaction reaches equilibrium. This is when we found out that the battery is 'dead'.

The battery has two terminals, one positive and one negative, with two different types of metals.  Floating inside the battery is also a supply of acid, which scientists would call an electrolyte.  This acid keeps the electrons flowing between the positive and negative terminals all the time.\n\nWhen you set up a wire loop, one end is connected to the positive terminal and the other is connected to the negative terminal.  The free electrons inside the battery like to flow from the positive down to the negative terminal.  Now they have a way out of the battery through the wire.\n\nThe electrons flow through the wire and anything else connected to it, like a small lightbulb.  Some of the electrons are used to make the filament inside the lightbulb glow red hot.  The rest of the electrons continue around the loop and end up at the positive terminal of the battery again.  This process keeps going until either almost all of the electrons are used up in the lightbulb (the battery is 'dead') or the circuit is broken.

You need a reference table and some instruction. Go to this site and scroll down to electrochemistry. Good luck!\nhttp://spiderpong.sitesled.com/chemistry_12_handouts.htm

Take the battery down to Radio Shack.

Uhhh connect the negative part of the battery to the negative plate, and connect the positive part of the battery to the positive part.

What you are doing is building a battery, an acid based battery.  take a lemon, get a strip of copper and a strip of zinc from chemistry class, or use pennies and dimes.  insert the metal stips in opposite sides of the fruit and connect a wire to each strip.  with this you will get about a .5volts, take 2 or three and wire is series and you can light a small flashlight bulb or run a small motor.\n\nsee the following  http://www.hilaroad.com/camp/projects/lemon/lemon_battery.html

make a mixture of half baking soda and half water. then apply it to where the acid is. This is great for when you have to clean the prongs on the battery. Be careful not to touch the acid.

try out an electrolysis experiment with the battery u wil get to know abt the charges of the battery the place where the metal move is the negative charged one and where the non metal moves tht is the positive terminal
