It sounds like you have nickel-cadmium batteries, since 7.2 volts is an integral multiple of 1.2 volts. You should notcharge a nickel-cadmium battery with any charger that is not specifically designed for it. The issue is that overcharging these batteries will damage them, and that the battery voltage alone is not enough to determine state of charge. (You have to measure the slope of the voltage, and detect the inflection point which occurs at full charge. This is a very specific thing, so the battery must be matched to the charger.)

A 19 V battery delivers 114 mA of current when connected to a 72 resistor. Determine the internal resistance of the battery.?
Internal resistance is approximately equal to 94.667
If the voltage in a circuit is 24 volt and the current is 2 A what is the total power in the circuit?
Power = E times I = (24 x 2) = 48 watts
A transformer has primary voltage of 240v and a secondary voltage of 48v what is the turns ratio of this transformer?
The turns ratio of a transformer is directly proportional to the voltage.To find the number of turns in the secondary, first calculate the voltage ratio.24V/115V is a 1:0.2087, if we use this ratio to calculate the turns we get.345 x 0.2087 = 72 turns.Another idea to apply (which says the same thing) is that the ratio of the voltages will equal the turns ratio. Here's how that looks:Voltageprimary / Voltagesecondary = Turnsprimary / Turnssecondaryor justVp / Vs = Tp / TsPlugging in the numbers will give us115 volts / 24 volts = 345 turns / Ts , and 115/24 = 345/Ts , and 115 x Ts = 24 x 345 , and Ts = (24 x 345) / 115 , and Ts = 8780 / 115 = 72 turns.
Font size is measured by what?
Font size is measured in points. 1 point = 1/72 of an inch. 12 point font is 12/72 inches high. 72-point font is 1 inch high.

How long to charge dead laptop battery?
Check and see how many Ah (Amper hours) your battery is. If it is for a gas/gasoline car, then it is probably around 42 Ah; batteries for diesel are usually around 72 Ah. Check the power of your battery charger. It should be something between 4-6 A. You must divide the battery capacity by the charger strength to get the time necessary. For example: your battery is 42 Ah and your charger is 6 A. Then the time needed will be 42 Ah / 6 A = 7 h. Charge your battery no longer than 7 h. Please note that overcharging the battery permanently damages it.

What are the differences between float charging and boost charging in solar power battery systems?
The difference between a float charger and a trickle charger is that the float has circuitry to prevent overcharging. It senses when the battery voltage is at the maximum level and temporarily shuts off the charge (floats voltage at zero or a very minimal charge until it senses that the battery output voltage has fallen, then resumes charging ). You can keep it connected indefinitely. A trickle charger, on the other hand, will charge no matter whether the battery is fully charged or not. So it needs to be connected and disconnected periodically. If left in place too long it'll eventually boil the electrolyte out of the cells or damage the plates. Trickle chargers will work to keep the battery charged if used once a month or so for a day or 2, but the float chargers can be left connected indefinitely without potential harm to the battery. For example, a 24 volt battery pack, comprising 12 2-volt flooded lead-acid cells, which has been deeply discharged, would normally be restored by a boost charge of approximately 2.4 volts per cell for a short time (perhaps around 72 hours). Once the collective cell voltage reaches a surface charge of 28.8 volts (2.4 volts x 12 cells), the charge rate would be switched to the sustained lower float- charging rate of typically 2.23 volts. Eventually, with the Boost charge removed, the surface charge will diminish slightly and the battery-bank voltage will stabilise at a preset float voltage, in the case of the example above to approximately 27 volts (2.23 volts x 12).

How do you recharge a dead car battery?
Depends how dead it is.Start off by checking the cell levels and topping them up with distilled water,nothing else,if one cell is MUCH lower than the others it can indicate a dead cell that has an internal short caused by sulphate deposits between the battery plates,if this is the case the battery is knackered.After topping up,leave the cell caps off and connect the + and - of the battery charger to the battery,making sure you have connected them the right eat + to+ - to -,plug the charger in then switch on,the battery if flat/low will draw a high current at the begining of charging (The ammetre will swing to right if a electro/mech gauge from 0 to about 10 Amps,depending on the capacity of the charger and the state of the battery)if its a charger with charging lights,more lights show a high current charge,the battery will pull a high charge for about 5 hours and as the battery charges up the amps it draws will slowly decrease to about a couple of amps.On average it takes about 12hours to fully charge a flat battery,if the battery has been excessively discharged it can take upto 72 hours with a 10 amp charger (no kidding!)Fast charging batteries should be avoided as it can and does damage them.The ONLY way to check that a battery is fully charged you will have to use what is called a hydrometer to check the electrolytes charge in each cell,insert the hydrometer in the first cell and draw up some of the electrolyte with the bulb ontop until the float starts to float (You are checking the fluids specific gravity here) most floats are colour marked red,orange,green,the higher the float sits in the liquid the higher the charge,look at the level of the fluid against the floating float,if fully charged the fluid level will be accross the green portion of the float,check each cell one at a time and rinse the hydrometer between cells with distilled water,just suck some up with the hydrometer and the squeeze it out.Each cell should hold about the same charge when fully charge,any cells that show low levels of charge may be dead say if you get 5 cells in the green and one in the red after 12hrs of charging the battery is knackered,it will start a car,but it wont hold a charge as the dead cell will cause a slow short circuit in the battery,replace the battery.Sometime if you charge the battery for a couple of days you may be able to recover a battery with a dead sell as the sulphate deposit might be dissolved removing the short,but best not to risk it though,nothing worse than a battery you cant trust!DO NOT USE A HIGH CURRENT CHARGER (50AMP+) TO TRY AND "BOIL" A BATTERY TO LIFE,YOU WILL OVERHEAT IT AND BUCKLE THE PLATES!!)When tha battery is fully charged,check the fluid level and top up if nesescary and replace the caps on the cells,leave the battery to degas for half an hour or so before using.Fully charged voltage after sitting for an hour after charging should be 12.8-13.8v,any lower replace battery.simply with a battery charger. you can also try jumper cables to charge it up enough.
