Hello,
I was reading your files, in VOL 1 dc/ Divider circuits and Kirchhoffs laws/Voltage divider circuits - 3/4s down, I found a diagram like this, figure A.
Please look at figure A. The voltage can be reduced between terminals 3 and 4, and I have no problem with that. But I am having a problem with terminals 1 and 2 connected together? To me its creating unnecessary current throw potentiometer, and I do not understand its purpose.
Please look at Figure B. I opened the circuit between terminals 1 and 2. The voltage can be reduced between terminals 3 and 4 as before.
Please explain why 1 and 2 are shorted?
