How to solve potentiometer questions
WebThe question which I've not written down to save space is to find the voltage across each resistor and to find the current through each resistor. Now before we start solving this, let's quickly go through a common mistake that I would do while solving problems like this. What I would do is apply Ohm's law to each resistor directly. Weband we have derived the voltage divider equation: The output voltage equals the input voltage scaled by a ratio of resistors: the bottom resistor divided by the sum of the resistors. The ratio of resistors is always less than 1 1 for any values of \text {R1} R1 and \text {R2} R2.

We’ve been given the value of the voltage source and both resistors, so all we need is to find out the current around the loop and the voltage drops over the resistors. And as soon as we find one, we can quickly use ...
WebMay 19, 2024 · Most potentiometers have a rotation range of about 270 to 300 degrees, with a typical mechanical resolution and repeatability of around 0.5% and 1% of full-scale value (between one part in 200 and 100, respectively). Note that there is a slight but distinct and important difference between a potentiometer and its junior sibling, the rheostat.
