Watts and Power

  1. May 28, 2008 #1
    I have a 38 watt amp and I'm trying to figure the Power it produces, but I'm not sure how to find the Velocity. Can anyone clue me in on this?
    And I know to use the P=V^2/R

    And sorry if this is in the wrong forum, I'm new.


    EDIT: I just found V=f/Lw (velocity=frequency/wavelength) but how do I find the frequency and wavelength?

    Go back to the source of your first equation:

    [tex] P = \frac {V^2} R [/tex]

    Find the meaning of each symbol, I'll bet that V is NOT velocity.

    I'll bet your 38 watt amp provides 38 watts of power.... :P
