1. Watts to Amps conversion... (score: 1): Author: <Tim.Mullen@trw.com>; Date: Mon, 24 Feb 2003 17:16:47 -0500; Does anyone happen to know the magic formula for converting Watts to Amps for AC current? I know that it's Watts = Voltage * Amps for DC, but I believe there's a "factor" in there for AC. I can't see; /html/shop-talk/2003-02/msg00058.html (7,803 bytes)

(score: 1): Author: Richard Welty <rwelty@suespammers.org>; Date: Mon, 24 Feb 2003 18:39:07 -0500 (EST); umm, if my vague memories of Circuits & Electronics 1 serve, there's no factor, it's just P=IE, same as for DC richard -- Richard Welty rwelty@suespammers.org Averill Park Networking rwelty@averillpa; /html/shop-talk/2003-02/msg00059.html (8,218 bytes)
3. RE: Watts to Amps conversion... (score: 1): Author: Hugh Fader <hfader@usa.net>; Date: Mon, 24 Feb 2003 19:24:16 -0500; You might be thinking of converting peak voltage or power to RMS. The factor is .707. But you want to use RMS which is the commonly used rating. As Richard Welty posted Watts = Volts X Amps. So if y; /html/shop-talk/2003-02/msg00060.html (8,712 bytes)
4. RE: Watts to Amps conversion... (score: 1): Author: "Randall Young" <Ryoung@navcomtech.com>; Date: Mon, 24 Feb 2003 16:33:01 -0800; Tim, I think you're talking about "power factor", which is the cosine of the phase angle, and varies depending on what the load is. An resistive load will have a 100% power factor, an inductive or c; /html/shop-talk/2003-02/msg00061.html (8,759 bytes)

How are you measuring the volts, RMS, Peak, or Peak-to-Peak?

(score: 1): Author: Donald H Locker <dhl@chelseamsl.com>; Date: Tue, 25 Feb 2003 11:03:03 -0500 (EST); The Volt-Amps drawn will be greater than the Watts on the nameplate, but without knowing the power factor or harmonic content of the draw, it's a crapshoot what exactly the factor will be.
