Power transfer by a non-ideal cell to an external resistor can be same for two different values. Out of which on value `(K_(1))` is less than internal resistance of cell and another `(R_(2))` is greater than internal resistance of cell then:

Options

A. `R_(1)` will give less internal loss
B. `R_(1)` will give more battery life
C. `R_(2)` will give less efficiency
D. `R_(2)` will give more battery life

Answer

D

Explanation

Internal loss `=i^(2)r` whre `i=(epsilon)/(r+R)`
battery life time `=("Battery capacity")/("Curent")`
