In the first part of Guenther's example the resistor os 1.12 kOhms, and in the second part it is 283.3 Ohms. 283.3/1120 = around 1/4 the value. If you also include the fact that the current is on for 1/2 as long then the power dissapation should be 1/8 as much. ????? ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=89554#m89812 Need assistance?
