Sure you can and you will end up with 36 volts. Connect them in Parallel and you will have 12 volts.
No chance, 12V (specifically 12.6V for cars) is the force that electricity flows through the wires, all these batterys are the same, but some just last longer (hold more juice) similarly all Alkaline batterys are 1.5V so you can put D batterys in place of AA batterys, they just last longer = more amp-hours
under neth the trigger
No no at all now.
wiis dont have batterys u plug it into the wall
Not in parallel NO - unless each charger is twice the voltage required for a single battery. For example if you had 2 x 12V batteries and placed the in series, you would have a 24V battery. If you had two 12v chargers and put then in PARALLEL with each other, you would then have a 12v charger with double the current handling. Of course if the chargers were 24v ones, then it would work fine. if you have 2 x 12v batteries (for example) and wished to charge them with separate chargers (actually quite a good idea), then each charger would be over each battery. So the batteries would be in series, the chargers would also effectively be in series too. Basically another way of looking at it would be two have a 12v battery with a 12v charger to your left and then on the right another 12v battery with a 12v charger on it. Yes you can connect the two together in series. The only slight caveat is that the chargers must be isolated from each other - and not for example a "dual output charger" which simply has an extra pair of leads but a shared charging system. - 12v + - 12v + ---------+-BATTERY---+----------+--BATTERY--+-------- - | |+ - | | + |=CHARGER=| |=CHARGER=| - <------------------------------- 24 v ----------------------------> +
you need a batery charger not batterys
No
put in batterys and pull trigger half way
did you put batterys
yes
Yes, if you put them in series.
The formula you are looking for is I = E/R. Amps = Volts/Resistance. If you say it is normally a 2 Amp circuit, it normally draws 2 amps. Therefore the original resistance offered to the 12v battery is 2/12 = 6 Ohms. If you then connect a 12 Ohm resistor in series, they are added, so R = 18 Ohms. Now if you put 12v across this circuit it will draw 12/18 = 0.66 Amps. Or If you just put a 12 Ohm resistor across the 12v supply it will draw 1 Amp. If the circuit is protected by a 2 Amp fuse, it will not blow, but the resistor will get hot.
