Baiscally, im in the middle of coursework (write up stage). I used a rotary potentiometer in series with a resistor, with voltmetres in parralel with both components. I could go and bore you with the details of the experiment, but i wont...
Basically, i had the variable and fixed resistor, thinking i would use these to make a potential divider. I have now realised that the rotary potentiometer (the one with the spindle that you turn to change resistance) serves as a potential divider.
So heres my question. In this scenario do both these resistors still make a potential divider? What is the effect of the fixed resistor on the readings of potential difference (voltage) across the potentiometer?
Regards
