Wire minus - to positive +. Know that this will increase the voltage but the amps will stay the same. Wire two 12 volt batteries together in series and you have 24 volts. Click the link.
It depends on the load and desired voltage. The voltage adds as you put batteries in series. Positive to negative, etc.
Normally putting the batteries in series would have more effect.
Putting batteries in series will up the voltage of the entire circuit. Certain things need higher voltage, so you put your batteries in series. Putting batteries in parallel will not up the voltage, but will let the current last longer. Watches would be more of an example for that. You want watch batteries to last long.
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
Take out the batteries out, replace new batteries, or put the same batteries back in. It will reset the high score on Bop It.
The formula you are looking for is Vt = V1 + V2.
Two batteries in series will cause the bulb to burn brighter.
Yes, if you put them in series.
2 batteries are wired in series then these 2 are wired in parallel with the other 2 which should also be wired in series. series is positive to negative and or negative to positive. parallel is pos. to pos. and neg. to neg.
Connected in series, yes.
A series circuit will produce more voltage. For example, two 12 volt automotive batteries both have a 600 amp capacity. Connect the 2 batteries in series and you will have 24 volts with 600 amp capacity. Connect the 2 batteries in parallel and you will have 12 volts with 1200 amp capacity.
You will get double the voltage.
