Re: Could UA be related to cellphones?

At what voltage? A watt at 3v and a watt at 12v are completely different
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.
A 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".
