For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.

Can a parallel battery supply more current?

This is the same as connecting 3 identical reservoirs to a pipe: you are not increasing the pressure. However, the parallel batteries (or reservoirs) will be able to supply more current (3 times, in the case of ideal batteries) when you reduce the resistance (make the pipe larger) The current won't be larger, since the voltage is the same.

What happens if a battery is connected in parallel?
