Variable Resistor/Potentiometer

  1. Jun 17, 2009 #1
    Ok, today in my Physics exam, we had to draw a circuit which involved a Potentiometer. Anyways, I was drawing the circuit and I had a mental blank of the potentiometer symbol. However, I knew that the diagonal arrow that you draw across a component means variable. I did that instead over a resistor symbol and I was wondering whether that is still a valid symbol to denote potentiometer/variable resistance or does it not exist at all? I remember seeing it somewhere but I wasn't sure whether it was correct or not.

    Yes, as far as I know it is still a valid symbol

    Yep, still see that frequently--as well as the arrow-wiper version of the symbol. the diagonal line isn't useful in showing a pot with both ends connected plus the wiper (three wire pot) though.
