How does the new energy battery cabinet dissipate heat
Let me try to explain it. First, let''s assume the voltage source has very low internal resistance compared to the resistor you are experimenting with, like, say, a 12-volt car battery. Now, you put your resistor R of, say, 1 ohm across the poles of the car battery. So 12 amps will flow, so 12*12 watts of heat come off. 144 watts, that''s a lot ... - Download [PDF]
