The charging scheme used in Figure P2.11 is an example of a constant-current charge cycle. The charger voltage is controlled such that the current into the battery is held constant at 40 mA, as shown in Figure P2.11. The battery is charged for 6 h. Find: a. The total charge delivered to the battery. b. The energy transferred to the battery during the charging cycle.
Hint: Recall that the energy, w, is the integral of power, or P = dw/dt.
