To Increase the Votage.....
If we connected in series current remain same and onlty
voltage will change.
In parallel current will be more and voltage remain same.

Answer / kasi

In series V = V1+V2+.... By Kvl
So If u want 3V, Two 1.5V are connected in series

Answer / dkmathur

Batteries are connected in series only to get higher
Voltage (the max. output power remains the same as of
single battery only) and are connected in parallel to get
more power/load (voltage remains the same as of single
battery).

Answer / ramkumar

want to get high voltage

Answer / kkk

Depending upon the voltage and current rating you want,
batteries may be connected in series / parallel or
combination of series & parallel. To get more voltage
keeping current / load same, add the batteries in series.
If you need more load to be connected without change in
voltage level (that of a single battery), connect them in
parallel. If you need higher voltage level than single
battery & require mor current, connect them in combination
of series & parallel as per requirement keeping the
following formulas in mind
1. In series, voltage increases as V = v1+v2+v3+....
2. In parallel, current increases as I = i1+i2+i3+....

Answer / rajesh tokalapudi

batteries r connected in series to increase the voltage
rating as current remains same in series circuit.They r
connected in parallel to get more current rating as voltage
remains same in parallel circuit.

Answer / santhoshkumar

to get maximum voltage.

Answer / azhar ali

Batteries are connected in series to increase the
voltage.The current remains the same.Series circuit has one
path through which electrons may flow.
1:- Total current I= I1=I2=I3,and etc.
2:- Total Voltage V=V1+ V2+V3 and etc.
3:- Total Resistance R=R1+R2+R3 and etc.
Follow the above rules if batteries are connected in series
the Total voltage will be the sum of the voltage of each
battery and the Total current will remain the same in the
circuit.
Connecting batteries in parallel increase the current and
Voltage remains the same.When you boost your car,you just
connect the booster across yours battery.Because you need
more current and same voltage.

Answer / satish

when batteries are connected in series the voltage is going
to be divided, so that, the total voltage appeared to be
effective.

Answer / gousejoshi

When battery is conected in series,we are getting the
uniform voltage.
