Op amps used : lm358
Image 'a' is inserted for reference.
In image 'b', a second op amp is introduced but with a single positive supply in contrast with the first dual supply op amp. The measurements taken with multimeter shown in image 'b' indicate that the voltage of the batteries seems to drop with time.
Image's 'c' measurements were taken after about an hour and they show that Vout has reached a negative voltage value. How is this possible with single positive supply voltage and why do the batteries seem to drop voltage?
Thanks for your time
