Engineering Linear potentiometer in a circuit problem

AI Thread Summary
To find the distance x of the slider from the left edge of a linear potentiometer with a total resistance of 470 Ohms and a length of 50mm, the output voltage (Vout) must equal 0 V. The equation Vout = Vin * (R1/(R2+R1)) is used, but it is noted that R2 and R3 are not in parallel due to R1's presence. The calculation attempts to determine the effective resistance, but the setup requires reevaluation of the circuit configuration. The problem highlights the importance of correctly identifying resistor arrangements in circuit analysis. Understanding these relationships is crucial for solving the potentiometer's output voltage scenario.

Homework Statement


The total resistance for the linear potentiometer (R1) is 470 Ohms, and its length is 50mm. Calculate the distance x of the slider from the left edge of the potentiometer for which the output voltage (V out) is 0 V.

Homework Equations


Vout = Vin * (R1/(R2+R1))

The Attempt at a Solution


R3 and R2 are parallel: (150*330)/(150+330) = 103.125 Ohms
(10)*(103.125) / [103.125+470(1-(x/50))] = 0V

No, R2 and R3 are not in parallel. R1 is in the way.
