    I can't understand how to translate this into math: potentiometer as voltage divider.

    Teacher gave us this circuit to analyze and we're supposed to use the voltage divider formulation: \[ V_{R1} = \frac{E\cdot R1}{R1+R2+R3} \] It gives me: \[ V_{R1} = 4.55\] \[ V_{R1} = 6.69\] \[ V_{R1} = 3.75\] The problem is, either I don't know how to interpret these numbers, or I'm not...
