[QUOTE="smoka, post: 5769031, member: 606721"] Well you're a real douchebag. You love to rant about how smart and great you are but you contribute 0 to the post. Why don't you post something helpful? Or do you just like to talk about yourself?? How does your post contribute to the OP??? Btw, being an electrician is nothing to brag about. I have several electricians that work for me, they are good guys, but I doubt many of them graduated high school. Techncally power equations are not part of Ohms law. They are so similar I always call it all Ohms law and most people do aswell. (especially since you use Ohms law in many of the power equations). So looks like I'm a little dusty on my circuit theory. Impedance = Voltage/Current = Resistance in DC Impedance = Phasor Voltage/Phasor Current in AC First off, the OP said he was using test tones and trying to find the output at only one frequency. I'll admit I was wrong when I thought I was calculating Real power, and instead it looks like the equation I gave was to calculate Apparent power (Vrms x Irms), measured in VA (not watts). And I never said clipping = thd. I just said that they both can occur when trying to get the most power out of your amp. Your inaccuracies are so bad they are quotable. [/QUOTE]
