Engineering Solving Circuits with a Potentiometer: Calculate R & Rx for 1A-10A

Click For Summary
The discussion revolves around calculating the values of a fixed resistor (R) and a variable resistor (Rx) in a circuit with an 110V source to adjust current from 1A to 10A. The potentiometer (Rx) is designed to allow maximum current flow when set to its minimum resistance and minimum current flow at its maximum resistance. Participants express uncertainty about how to approach the problem, particularly regarding the use of a potentiometer in circuit calculations. The relationship between resistance, voltage, and current is critical for determining the appropriate values for R and Rx. Understanding these principles is essential for solving the circuit problem effectively.

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.
