A cell of internal resistance 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 loadEnergy dissipated in the complete circuitWhich of the following gives the efficiency in this case?
