Question

three electric cells of potential difference 1.5v each have been connected as a battery the potential difference of the battery will be.................. v.

Answer 1

When electrical cells are connected in series as in a battery, the potential difference of the battery is the sum total of the potential differences of each cell.

In this case, the potential difference of each cell is 1.5 bolts.

Therefore the potential difference of the battery is the sum total of their potential differences, I.e., 1.5+1.5+1.5 = 4.5 volts.

Answer 2

Hey Mate...!

Here's ur ans. ⬇


Battery is the combination of cells .
Hence the sum of the potential difference of all the cells is equal to the potential of the battery

1.5 + 1.5 + 1.5 = 4.5 Volt
