SUMMARY

The discussion centers on calculating the power output of a 38-watt amplifier using the formula P = V^2/R. Participants clarify that the variable V in this equation does not represent velocity but rather voltage. The user also explores the relationship between frequency and wavelength with the equation V = f/Lw, indicating a misunderstanding of the terms involved. Ultimately, it is established that the amplifier produces 38 watts of power, and further clarification on the definitions of the symbols in the equations is necessary.

PREREQUISITES
  • Understanding of electrical power formulas, specifically P = V^2/R
  • Familiarity with basic electrical concepts such as voltage, resistance, and power
  • Knowledge of wave properties, including frequency and wavelength
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Research the definitions of electrical symbols in power equations
  • Learn about the relationship between frequency and wavelength in wave mechanics
  • Explore practical applications of P = V^2/R in audio equipment
  • Investigate how to measure voltage and resistance in amplifiers
USEFUL FOR

Audio engineers, electronics enthusiasts, and anyone involved in amplifier design or troubleshooting who seeks to understand power calculations and the underlying principles of electrical formulas.

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
