The difference between the electrostatic potential of the positive end the negative end of an electric cell is the of ................ the cell.

Answer»

E. m. f of the CELL (potetential), note that if q is negative, and its sigh should be USED in the equation.

Even the system consisting of a negative and a POSITIVE point-like charge has a negative potential energy.

A negative potential energy means that WORK MUST be done against the electric field in moving the charges apart.
