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