Dave also cannot read.  I didn't just key 160 Watts for 500 msec.  I keyed
160 Watts for 2 seconds.

So following your train of thought Peter:

160 W for 2 sec
640 W for 500 msec
6.4 kW for 50 msec
64 kW for 5 msec!!!

A Joule is 1 w-sec as defined by my IEEE dictionary.

So 160 Watts for 2 seconds is 320 Joules.
640 Watts for 500 msec is also 320 Joules.
640 kW for 0.5 msec is ALSO 320 Joules.

I guess Dave is the one who doesn't understand conservation of energy and
how things really work.

Yes, the specious blather on the list IS entertaining.

73,
