FET as a voltage controlled resistor VS using a normal resistor?

[Simmon]

FETs used as voltage controlled resistors

What is the difference between using a FET as a voltage controlled resistor VS using a normal resistor?

Adjust the voltage on a FET to the SAME value as a fixed normal resistor, what would be the difference?

you have already asked this in your other thread to which I have given one reason
