$begingroup$ The battery ends don''t have an absolute voltage (relative to ground) of 1.5V unless the negative terminal is shorted to ground. They have a voltage between the anode and the cathode of 1.5V. The absolute voltage of either end (and your own absolute voltage before touching it) is completely uncertain, and can fluctuate wildly if it is, for example,

"Ground" vs. "Earth" vs. common vs. negative terminal
A. The positive terminal in a circuit is what creates voltage. Voltage is a potential, so given that it is the positive ions in, say, a battery, which are generally fixed in place, it makes sense that the + terminal in a circuit would create voltage.. B. The negative terminal in a circuit is what provides current. Current is the flow of electrons, and that flow is towards the terminal
ELI5. what is negative voltage? : r/explainlikeimfive
Negative voltage is simply any place where current would want to flow from zero to that point. If I had a car battery (12V) I could say that the positive terminal is 0V and the negative terminal is -12V and all the math works out the same. I can also say the negative terminal is 100V and the positive terminal is 112V and still nothing changes.
Voltage on negative side
Do you mean voltage drop in the negative lead of battery, or power supply? Same as positive side! The "negative" just refers to the polarity or direction of flow. If enough voltage is lost or circuit is open the consumer will get less or no current. Draw a picture. Like Reply. W. Thread Starter. Webby. Joined Jun 15, 2008 66. Jul 25, 2014 #8
