Discussion Overview

The discussion revolves around calculating the power output of a 38 watt amplifier, focusing on the relationship between power, voltage, and resistance. Participants explore the relevant equations and concepts involved in this calculation.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant seeks to calculate the power output of their 38 watt amp and expresses confusion about finding velocity in the context of the power equation P=V^2/R.
  • The same participant later introduces the equation V=f/Lw (velocity = frequency/wavelength) and questions how to determine frequency and wavelength.
  • Another participant suggests revisiting the definitions of the symbols in the power equation, implying that V may not represent velocity.
  • A humorous remark is made about the amp's power output, suggesting it simply provides 38 watts of power.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correct interpretation of the symbols in the equations, and there is uncertainty regarding the definitions and calculations involved.

Contextual Notes

There is a lack of clarity about the definitions of terms used in the equations, and the discussion does not resolve how to find frequency and wavelength in this context.

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.

Thanks

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:

P = \frac {V^2} R

Find the meaning of each symbol, I'll bet that V is NOT velocity.
 
Haha right.. sorry
 
I'll bet your 38 watt amp provides 38 watts of power... :P
