Unformatted text preview: the rate P = i E if the current and emf are in opposite directions. For battery 1 the power is P 1 = (0 . 50 A)(12 V) = 6 . 0 W and for battery 2 it is P 2 = (0 . 50 A)(6 . 0 V) = 3 . 0 W . (f) and (g) In battery 1, the current is in the same direction as the emf so this battery supplies energy to the circuit. The battery is discharging. The current in battery 2 is opposite the direction of the emf, so this battery absorbs energy from the circuit. It is charging....
