Question

A dry cell usually has a small cap at one end and at flat surface at the other end.which of the two is at a higher potential

Answer 1

The flat end is actually the negative terminal of the dry cell and the cap end is actually the positive terminal of the dry cell.

And we all know that the electricity flows from the negative terminal towards the positive terminal.

That's why the cap end terminal or the positive terminal of a dry cell has the higher potential than the flat terminal or the negative terminal of that dry cell.

Answer 2

Explanation:

we know that electricity flows from negative terminal towards the positive terminal. therefore positive terminal of the cap end terminal has higher potential.
