Hi all, Forgive the OT (and my ignorance of how electricity works), but I couldn't seem to readily locate the answer to a question I have regarding electricity usage. I have several gadgets (flashlight, cordless screwdriver, etc..) that are rechargeable and the directions to these products state that once the product is fully charged I don't have to unplug it. The question I have is if there is no more electricity being used, then why does the AC-to-DC converter remain warm (very warm)? Doesn't the presence of heat indicate an electrical discharge/action is taking place? This same question bothers me about my SRS sub-woofer...it has an auto-on feature, so that the amp is supposed to turn off if no music signal is present (after some elapsed time period), however, the heat sinks on the back of the sub-woofer are still fairly warm even if it's not been used for several days. TIA to anyone with the patience (and time) that can explain this to me (in oh, let's say, 3rd grade level knowledge). :-) Ray Shahan "There is so much good in the worst of us, and so much bad in the best of us, that it behooves none of us to talk about the rest of us" --Robert Louis Stevenson? ##################################################################################### This e-mail message has been scanned for Viruses and Content and cleared by MailMarshal ##################################################################################### * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
