Technically, are we not limiting the current we are actually limiting.The voltage correctThe current is constant at five milliamps, so all we are changing is the voltage in the circuit.I love this video, but I technically think that we are really changing the voltage.Because the current draw stays the same correct

2000 ohm / 1000 = 2K not 220 or 22 ohm

so its like wasting 10volt as heat? or it will remain turn on 6 times longer as compared to 12volt load? with the same battery
