fet variable resistor
How can i use a FET or transitor in a circuit to be acting like a variable resistors?
I think i use DC voltage to change the FET or transitors resistance
But what are these circuits called and where can i find a schematic network that was a FET or transitor that is used as a linear or audio rheostate or voltage divider resistor ?
