Energy = I²R * t. What is the total power supplied? The total load resistance (including wires) is 12V/60A = 0.2 ohms so the total power supplied is 144/0.2 = 720 watts. What is the energy lost as heat in the wires? Power lost in the wires is 60² * 0.01 = 36 watts so energy delivered is this number multiplied by time (2 seconds) = 72 joules.
