At what voltage? A watt at 3v and a watt at 12v are completely differentA watt is a watt. How do you come to the idea that a watt at 3v is different to one at 12v? I know you want to say that a watt at 3v is 0.333 amps and that a watt at 12v is 0.0833 amps. But the amperage is not relevant, a watt is a unit of work, not a pressure as in volts or a flow as in amps. Further we're talking high frequencies here which as transmitted (I would imagine but don't know) would be in class "C".
watts.
Perhaps the scale should be milliamps instead of milliwatts. Whatever. The
transmit power of a cellphone is a fraction of the power floating around
within an automotive system. That's what I like to believe.
