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  Which of the following gives the efficiency in this case? a) b) c) d) 3537

(d)

Assuming current flows through the circuit Energy dissipated in load Energy dissipated in the compete circuit  The efficiency Relation between resistance, mass and cross-sectional area   Next Question :
