What is the pinch off voltage for a JFET?
JFET Pinch off voltage “Pinch-off” is not locked. During pinch-off operation, the discharge current does not drop to zero. Instead, the Id current becomes constant, remaining relatively independent of the…

Get Here about Jfet , How Jfet works. Basic theory of Jfet.
Why JFET is always reverse biased?
Reason for JFET is always reverse biased Due to “depletion region” surface reduction increases the resistance of the drain source and reduces the current flow and so JFET is always reverse biased….
What will happen if the positive VGS (voltage across the gate and source) is applied to the JFET?
Why vgs is negative in jfet (Junction field effect transistor) The main function of jfet is to modulate the current between the channel and the source with the variation of…
