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. |
