A cell of internal resistances r is connected to a load of resistance R . Energy is dissipated in the load, but some thermal energy is also wasted in the cell. The efficiency of such an arrangement is found from the expression ( Energy dissipated in the load )/( Energy dissipated in the complete circuit) Which of the following gives the efficiency in this case?
