A standard D cell flashlight battery is connected to a load of 3 Ω. After 6 hr of intermittent use the load voltage drops from an initial 1.5 V to a final useful voltage of 0.9 V.

(a) Calculate the internal resistance of the battery at the load voltage of 0.9 V.

(b) Calculate the average value of voltage V during the useful life of the battery.

(c) Calculate the average value of current I during the useful life of the battery.
