Homework Statement



There's an 110V source and two resisters in series. The first resister, R, is a fixed resistor. The second resister, Rx, is a variable resister (a potentiometer). The potentiometer is to be designed to adjust current I from 1A to 10A. Calculate the values of R and Rx to achieve this.

Homework Equations





The Attempt at a Solution



I have no clue where to start. I have never dealt with circuit problems that involved a potentiometer before.

The maximum current will flow trough the circuit when the potentiometer is at its minimum value and the minimum current when it is at its maximum value.
