I have a question about the N-JFET.Assume it operates at the linear region and it acts like a voltage controlled resistor. Can we say that if Vdg(drain-gate voltage) is increased then the resistance of the JFET is increased?I have just started reading about JFET and I find them very confusing.

Also I found this video , I don't understand why most have Vds and Vgs which is very confusing...

  • \$\begingroup\$ doesn't the drain-gate voltage increase the resistance? \$\endgroup\$

  • \$\begingroup\$ for N channel jfet the gate voltage is negative wrt to source, the more negative it is the less current from source to drain \$\endgroup\$

  • \$\begingroup\$ do you mean a more negative gate-source voltage will increase the source to drain resistance? assuming drain-source voltage is such that if gate-source voltage varies the device remains in ohmic region? \$\endgroup\$
