Interesting topic. I’m a student myself but I do not have intelligence about electrical engineering though. But so far, I only understand that potentiometer controls voltage which makes them a passive device while the rheostat controls current. For example, the potentiometer can only control audio equipment via volume controls. However, in rheostat, adjusting its volume would make rheostat resistance change the electric current through the device changes, which then changes its volume frequency.

Here’s a short explanation: rheostat is another function of the potentiometer.
