SUMMARY

This discussion clarifies the behavior of two 12-volt batteries connected in parallel and series. In a parallel configuration, each battery supplies 3A, resulting in a total current of 6A through a 2-ohm load, maintaining a voltage of 12V. Conversely, when connected in series, the batteries provide a combined voltage of 24V, leading to a current of 12A through the same load. The parallel setup allows for longer discharge times due to increased capacitance, while both configurations ultimately deliver 12A in total current under specific conditions.

Hi.

Lets say I have two batteries{each one has a 12 volts} connected in parallel circuit with a load of 2 ohms.This means,that each battery will force a current of 6A through the circuit and we will have 12 amperes through the circuit.
Is this correct.Does the total amount of amps in the circuit will be 12?

Now what if the battery are connected in series.The the voltage will be 24v ,and with a load of two ohms,the current in the circuit will be 12 amps.So according to this, adding battery in series,increase the current two.The only difference between the two will be in the capacitance.The parallel circuit have two cathodes so it will have more charges, and will last a longer time.Both circuit will have 12 amps, but the parallel will last longer.

I know that I missing something, so if anyone can help... thanks.

If both batteries are in parallel each one supplies 3A making a total of 6A that flows through the load.
 
The voltage from batteries in parallel is the same. That is, having two 12 volt batteries in parallel only applies 12 volts to the circuit, not 24. So with 2 ohms of resistance you have 6 amps flowing through the circuit, with 3 amps being supplied by each battery.

In series it is the opposite. Two 12 volt batteries in series supply 24 volts to the circuit. So with a load of 2 ohms you have 12 amps flowing through the circuit.
