How Do You Calculate Slider Position on a Potentiometer?

AI Thread Summary
To calculate the slider position on a 10 kΩ potentiometer with a 5 kΩ load when the voltage across points 'XX' is 3 V, a voltage divider approach is recommended. The circuit can be modeled with Kirchhoff's laws, where the total current entering a junction equals the total current leaving. The voltage across the potentiometer's segments can be used to derive the necessary equations, ultimately leading to a quadratic equation. The correct slider position is determined to be 0.5, indicating it is halfway down the potentiometer. Understanding basic circuit principles like KCL and Ohm's law is essential for solving such problems effectively.

Sorry to have to ask, you replied to James saying that 5k was correct however to Mark you have said that the 4&6 options are correct.
Because Mark's question was a bit different.

However I have resistor 10k-R in parallel with the 5k resistor where as diagram #40 has it the other way round. Will this matter?
Your solution looks correct to me.
