Dear Andy, LF Group At 08:46 11/11/2002 +0000, you wrote: You then conclude the internal circuit is either a Thevenin source (an ideal 1V voltage source with a 1-ohm series resistor) or a Norton source (an ideal 1A current source with a 1-ohm shunt resistor). Using standard laboratory equipment, how could you determine which one it is. Well, it's hard to be certain, but if the box has a label on the back which says something like "use 275,000 AA cells - observe correct polarity", then it is probably the Norton current source one...
