  1. Mar 1, 2009 #1
    1. The problem statement, all variables and given/known data

    What of the following is measured by the energy dissipated when a cell drives a unit charge round a complete circuit?

    A- Resistance
    B- Power
    C- Potential Difference
    D- e.m.f

    3. The attempt at a solution

    e.m.f is energy converted from non-electrical to electrical form when 1 C of positive charge pass through a cell.

    P.d is the energy converted from electical to other forms when 1 C of positive charge passes between 2 points.
