Question

three electric cell of potential difference of positive and negative and of electric is the dash of the cell​

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

The positive terminal is called a cathode and the negative terminal is called an anode. This current can be thought of as the flow of positive charges, even though it is usually electrons, which have negative charge that carry current in a copper wire circuit.
