[QUOTE="ahole-ic, post: 7626184, member: 619324"] [URL="http://www.kpsec.freeuk.com/components/diode.htm"]Diodes[/URL] Forward Voltage Drop Electricity uses up a little energy pushing its way through the diode, rather like a person pushing through a door with a spring. This means that there is a small voltage across a conducting diode, it is called the forward voltage drop and is about 0.7V for all normal diodes which are made from silicon. The forward voltage drop of a diode is almost constant whatever the current passing through the diode so they have a very steep characteristic (current-voltage graph). Wiring them in parallel reduces the amount of dropped voltage. If you try it yourself you will see. I use that a lot when making PCM's for alternators. [/QUOTE]
