I can't figure out what resistance values to use....

[QUOTE="Megatronlol, post: 6068662, member: 388133"] [IMG]https://imgur.com/a/BCk2QVg[/IMG] I started an electronics program recently and I am a month into it so I am quite new at this. I have a problem involving a potentiometer and I don't understand how to compute the voltages because I don't know what I am supposed to use for my resistance values. I know that in series the total resistance is the sum of the individual resistors. I assume that since R1 = 330Ω and R2 = 470Ω that I am taking the pot from 1Ω to 1000Ω and using a minimum value of 801Ω and a maximum of 1800Ω and using my voltage divider formula but that answers that I get don't match the measured values from the lab. In the lab I measured a maximum voltage of 8.13V and a minimum voltage of 2.65V. Can anyone offer any insight as to what resistor values I would be using for my voltage divider formula and why those values? Thanks.
