it has 400 watts
In the United States the maximum output of an FM station is 100,000 watts. Some older "grandfathered" stations transmit at higher power levels, such as WBCT in Grand Rapids, Michigan (320,000 watts). http://www.fcc.gov/mb/audio/fmclasses.html
Yes it does, it is located behind the am/fm radio, its nothing to brag about, I think it something like 40 watts or something. I recently replaced my radio and saw it when I pulled out the old head unit...
One million watts
A small battery AM or FM radio uses as little as 3 v at 10 mA, that is 0.03 Watts. A typical DAB radio might used 6 v at 250 mA, which is 1.5 Watts, or 40-50 times as much.
Not legally, no.
Watts
The power required is(6) times (the amperes of current the radio draws when it operates) watts.
25 watts woulod be an average wattage for a radio... i think :)
300 Watts!
Four watts out of the box, which is the legal limit set for CB radios by the FCC.
Radio waves are energy. Electromagnetic energy to be exact. The amount of energy a radio wave has will depend on the amount of power the transmitter has, the amount of amplification, the quality of the cable connecting it to the antenna and finally the antenna. The amount of energy is usually measured in watts.
I am not sure, but you can look at the back of your TV set. Most electrical equipment has its specifications there - if it doesn't state the watts, you can multiply amperes x volts.
