How do i calculate the duty cycle of Lead-Acid battery  and  Ni-Cd battery?
604177
well, it would differ from every kind of batery. the duty cycle would be the bateries best discarge per cycle(if that is what you are talking about) deep cycle bateries are capable of going into a deeper discharge on each cycle(charge and discharge)

1) Balance the reaction equation:\nPb(NO3)2  + 2 LiBr -> PbBr2 + 2LiNO3\n\n2) Calculate the amounts we start with\nPb(NO3)2 :  2.05 L * 0.0550 mol/L = 0.1128 mol\nLiBr : 1.52 L * 0.0618 mol/L = 0.0939 mol\nAs we need 2 moles of the latter for 1 mole of the former, the reaction is limited by the amount of LiBr\n\n3) Calculate the amount of PbBr2 produced\n0.0939 mol of LiBr will react with 0.470 mol of Pb(NO3)2 to produce 0.0470 mol of PbBr2. This is 0.0470 * (207.2 + 2* 79.9) =17.249 gram\n\n4) Calculate the yield\nThe yield is 15.784 / 17.249 = 91.51%

The "power" in any electric current is 'voltage'.\n'Voltage' is the measure of the potential difference of electrons between two substances, and therefore the potential for electrons to be transferred between them.\nBatteries generate electricity through any one of several electrochemical reactions.  \nTwo different types of metals are placed in a catalyst (usually a liquid).  When a circuit is completed between the positive side and the negative side, electrolysis occurs - the above mentioned transferring of electrons through chemical reactions from one metal to the other.  The difference in potential felt between the  positive and negative charges (giving off an electron results in a positive charge, accepting it results in a negative charge) is again your volts.\nThe reaction continues until the battery reaches homeostasis (equilibrium, balance).\nIn some kinds of batteries applying an outside electric current properly can reverse the process - allowing you to recharge the battery.\nRechargeable batteries eventually become exhausted because of of oxidation of the polarizing metals or due to a 'memory' buildup.  'Memory' refers to a battery that is not completely discharged before it is recharged.  This is the major reason for the degradation of rechargeable battery life cycles.

It all depends on the type of battery, and charger you use. The latest duracell NiMh batteries can be charged in 30 minutes or less. These chargers have a small built in cooling fan.\nA 9 volt? Be sure the charger can charge NiMH....and not just alkaline. If the battery is warm, there's a good chance it is taking a charge. You can always test it with a cheap radio shack tester. I reccomend getting one anyhow, considering how we constantly use batteries with all of today's whiz bang technology.

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

P= work/time and work is = to force x distance so its 500x4 =2000joules\nand 2000/4 =500 watts

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!

composed of either nickel cadmium, nickel metal hyrdride of lithium ion technologies. These types of computer laptop battery technologies, as so many elements of the high-tech world, are better known by their short abbreviations:\n\nNickel cadmium is known as NiCad\nNickel metal hydride is known as NiMH\nLithium ion is known as Li-Ion.\n\nThere are some differences between two nickel-based laptop computer battery technologies. (The NiMH version is the newer of the two versions of computer laptop battery units.) The NiMH computer laptop battery offers higher energy density than does the NiCad version. Generally speaking, the NiMH computer laptop battery delivers approximately 100% more capacity that its nickel-based counterpart.\n\nThe NiMH computer laptop battery also does not suffer from what is known in the industry as "memory effect." This is the effect in which unless a battery is drained completely before each recharging, the computer laptop battery will end up ultimately never fully recharging. The final result of the memory effect is a serious limitation of the expected lifespan of the subject computer laptop battery.\n\nOn an unrelated note, because the NiMH computer laptop battery does not contain the same heavy metals as theNiCad technology, it is more environmentally friendly. A significant problem in recent years has been the increase in heavy metals and products like some computer laptop battery units containing heavy metals that have found their ways into municipal landfills causing serious environmental damage.

You'll need, as the name may suggest, a voltmeter.  Also applicable is a multimeter - which you'd then set to voltmeter mode.\n\nAt which point you'd just put one contact on one one end of the battery, and one on the other, and see what the equipment reads.\n\nMy money's on 1.5V :)

That second reaction should be Pb(s) + Cl2(g) ---> PbCl2(s).  Reverse the second reaction and then add the two together and you will get the resultant reaction.\n\nPbCl2(s) ---> Pb(s) + Cl2(g)    H = +359.4 kJ\nPb(s) + 2Cl2(g) ---> PbCl4(s)   H = -329.2 kJ\n\nPbCl2(s) + Cl2(g) ---> PbCl4(s)  H = +30.2 kJ

well you need the power factor as well, From O/P KW to I/P KW by I/P KW = O/P KW / Efficiency; I/P KVA = I/P KW / power factor; I/P Current = I/P KVA / (V3 x 480); V3 is a 3 phase motor is used. so simple.

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.

On a battery, you have two terminals- a positive and a negative.  As a result, the net charge is 0.  Also, a battery is the source of 'power' in an electrical circuit, it is direct current (DC) instead of alternate(ing) current (AC).  The battery produces a certain number of Volts and from that, you can find the current at different points in the circuit, as well as the number of amps.  (I hope this is what you are talking about)

Both batteries and condensers store electrical energy.  A battery (actually a set of two or more cells) stores chemical energy while a condenser stores static electric charge. The battery voltage depends on the chemical and metals combined and the number of cells placed in series while the voltage of a condenser depends on the voltage of the source that charged it.
