thank you dude at last can you just attach a image of it there are multiple images showing when i type potentiometer or variable resistor the physical image of it

As I said, there are many varieties . . . the symbol is just that, a symbolic representation of the type of thing, not the specific variation.

There are mainly two kinds:

  • ones used to be rotated by the user of equipment - like amplifier gain control,
  • ones used to regulate some conditions and mostly never used again.
