When batteries are connected in series the voltage increases
but the current remains unchanged, how can this be?

When you consider ohm's law. i.e.
If voltage increases, current increases, providing
resistance remains the same.

Answer Posted / vinamra

as we know that battery are voltage source,so whenever we
will connect the voltage source in series then the
resultant voltage will be addition of that sources,but
current is depend upon the load so in this case current
will not increase but the ampear hour capacity will be
increase
