I need to make a wheatstone bridge using a potentiometer of 10KΩ, where when in 0Ω the output voltage must be -3V and when in 10KΩ the output voltage must be 8V. I tried to calculate several times using Kirchhoff, but I did not succeed, could a good soul be able to help this young student?

 

What do you think is a Wheatstone bridge?
Draw a circuit diagram of what you are proposing. Show all known voltages.

You say you tried multiple times. So show your best attempt. Describe your approach.
