Heh, yes, this seller made me confused too, with his item price configuration
. Weird, why did he pack multiple items under the same item ID...
I just measured the connectivity between the red wire and the pin 18 - seems good, almost zero (some 0.7 ohms from the multimeter wires themselves).
But still I'm not 100% sure - sometimes the electric components of a device also might have really low resistance, and it gets even more confusing if there are some capacitors in between - they tend to completely screw up resistance measurements.
To be sure that the resistance measured is actually for the wire itself and not for some electric components, I should cut the cable from the device, but I don't want to do that.
I'll now measure voltage on that wire with the device connected to my PC, and if it will be 5V then the next step - cut the wire and test how many mA does it consume. If it consumes a notiecable amount (50 or more mA), and is +5V and shows close to zero resistance when measured against HDMI pin 18, then it must be the power wire, right?
What is the chance that there might be some another HDMI wire which seems to act exactly as a power wire, but is not a power wire?
