Field Effect Transistors (FETs) Quiz

What are the two basic types of FETs?

• JFET and MOSFET

• JFET and BJT

• BJT and JFET

• BJT and MOSFET

What are the components of a JFET?

• Emitter, Base, Collector

• Gate, Source, Drain

• Source, Drain, Gate

• Collector, Emitter, Base

What is the function of the gate in a JFET?

• Connects the source and drain

• Acts as an insulator

• Controls the flow of current through the channel

• Forms the depletion region

What is the main difference between depletion mode and enhancement mode FETs?

• The material used in construction

• The presence of a physical channel between source and drain

• The type of insulating layer

• The requirement of gate voltage to form a channel

What is the function of the metal oxide in a MOSFET?

• Connects the source and drain

• Controls the flow of current

• Acts as an insulator

• Forms the depletion region

In which mode does a JFET operate by default?

• Enhancement mode

• Depletion mode

• Forward bias mode

• Reverse bias mode

What happens if the gate of a JFET is forward biased?

• The depletion region grows

• The channel narrows

• The current flow increases

• The component is destroyed

What is the threshold voltage in a MOSFET?

• The maximum voltage allowed at the gate

• The voltage at which the component is destroyed

• The minimum voltage required at the gate to create a channel

• The voltage required for the gate to be reverse biased

Which type of FET can work with zero bias, reverse bias, or forward bias at the gate?

• Both JFET and MOSFET

• JFET

• Depletion mode MOSFET

• Enhancement mode MOSFET

What is the main function of the gate in a MOSFET?

• Connects the source and drain

• Forms the depletion region

• Acts as an insulator

• Controls the flow of current
