pon a time, I had a boss who insisted that if you put 1 million 1.5V

Actually... That might work for a while with ZERO load. They made some

monstrous 'piles' in the 1800s to experiment with high voltages (not that

high, I'm sure).



You most certainly would get something other than 1.5V (if that's what

you meant to write).



But, if the voltmeter imposed almost any load, the mismatches in internal

resistance of the cells would quickly ensure that you got something

"other than 1.5 million volts acrosst 'em", as cells began to short out

under their mis-matched imposed voltage.



That's why we use resistor ladders cap-to-cap across series capacitors in

a high-voltage circuit. They're not just for the 'bleed' function. We

even called them "equalizer resistors".



(sorry, I just had to say "acrosst"! G)

Since you said "accrosst," I now feel the need to punch YOUR lights out ;-)
