Marcus spotted a typo in my recent post about joules and watts (in the "watt-seconds" thread). I wrote:
ORIGINAL 1 V.A = (1 J/C).(1 A) = (1 J/A.s).(1 A) = 1 J.s = 1 W The second last expression should have been J/s instead of J.s CORRECTED 1 V.A = (1 J/C).(1 A) = (1 J/A.s).(1 A) = 1 J/s = 1 W Thanks to Marcus and others who have informed me of this error. Regards, Bill Hooper physics professor (retired), Florida, USA P.S. I have here reverted back to using the dot-on-the-line rather than the more correct raised dot to show multiplication, since some of you did not receive it in the proper form. (Many of you got the numeral 7 instead.) I think maybe in my zeal to type in all those special raised-dot characters in the original message, that I got carried away and put one in where it did not belong. ======================== Keep It Simple - Make It Metric! ========================
