Question

eletric cells haveing 2v potential difference each have been connected in the form of a battery. what wil be the total potential difference of the battery in both cases

Answer 1

Now,

The voltage sources should always be connected in series

And if there are current sources then should be always connected in parallel

Why?

Well the potential in parallel is always the same and the current in series is always the same

So if we connect two voltage sources in the parallel then it will contradict the above statement Hence, two voltage sources will always be connected in series with each other

The potential difference between any two individual cells will be 2 volts

But the net potential difference will be 4 volts

So, a battery of 4 volts will be formed
