I was just curious and did a little setup with a mosfet and a potentiometer checking the resistance of the drain/source channel at different gate voltages, hm interesting I only did a rough check and could do a proper setup and take down v/R details and plot them on a graph but usually are mosfets "linear" ? are their carachteristics repeatable or are they quire variable like BJT's (for example the 2N2222 will from from a beta of 50 to 300 !)
