Hi Everybody! I have a question that I would like answered.... This question doesn't have much to do with SI, but, with the "plethora" of electrical knowledge available in this forum, I expect that someone may know the answer I am searching for... The question is: How long can I expect '2' alkaline D cell batteries connected in series to provide a relatively constant current of 0.3 Amps? i.e. 3 volts / 10ohms = 0.28 to 0.30 Amps Thanks, Mike ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
