1.	For low value of VDS, the JFET behaves like a __________(a) Voltage Variable Resistor(b) Constant Voltage Device(c) Amplifier(d) SwitchI had been asked this question in an interview.Enquiry is from The JFET Volt-Ampere Characteristics topic in division Field-Effect Transistors of Electronic Devices & Circuits
Answer» CORRECT choice is (a) Voltage VARIABLE Resistor To elaborate: When VDS voltage is very less, there will not be much current flow, SINCE as the VDS changes, the current value changes very LITTLE. HENCE we can say that FET works as a voltage controlled Resistor.
