RMS Power?

I often see power specifications like "100W RMS".  There is no such thing as RMS power.  Of course, you can calculate RMS value from any curve, including power curve, but it won't represent anything.  "Real" power representing heat dissipated in resistive load is "Average Power"   Pavg=Vrms*Irms.   In case of sinewaves Pavg=0.707Vpeak * 0.707Ipeak = 0.5Ppeak,  or Ppeak = 2Pavg. 

Term "RMS Power" or "watts RMS" is a mistake, very common in audio.

Hmmm - I think I’ll elect to - NOT loose any sleep over it.


Umm, it’s “lose”, not “loose”. Uggghhhh!

@sleepwalker65 - sorry about that.

Simply "typo" that I missed - it can happen to anyone - at some point

Happy Listening :-)

I'm not sure I understand the point of this post. Like it or not, RMS is the governing law of this electronic land. That's the formula you use to get rectified DC from the secondaries of your transformer and it's the formula you use to describe the gross power coming off the output posts.
