How does a multimeter know which side is positive and which side is negative? Let's say I have an non-conventional multimeter, whose two probes are of the same color (say white); and a battery whose polarity isn't labeled. If I place one probe on one end of the battery and the other probe on the end of the battery and it reads, say positive 9V, then how would know which end is positive and which end is negative?
Thank you. I now understand better.
Bob is back! Glad to see you have access to your videos. Please upload the op amp series as soon as you can.
