Sereies, with each cell about 2.2volts
Battery cells are conneted in series. Each cell of a 12v battery averages 2.1v when charged. SERIES 2-4-6-8 and so on
Series.
You would get a high circulating current through both cells, possibly enough to do significant damage to both the cells and to you, depending on the capacity of the cells. Technically, they would actually be connected in series, not parallel!
Battery
parallel
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
as the given cells have the same current flowing in through them (current flowing through the cells connected in series is equal to the current flowing when connected in parallel ) equate the formula's of cells connected in series and cells connected in parallel.thus by equating we get the value of the internal resistor as 2 ohms.
4.5 volts in series; 1.5 volts in parallel.
You would connect them in parallel to increase the amerage. If you connect them in series it would increase the voltage. Connected in series-parallel would increase both voltage and amerage.
Battery Pack.
Twelve volt batteries contain a series of 6 cells in the series.
Total voltage output of 5 2v cells connected in series would be 10v
