Electrical Engineering Laboratory II Quiz

David, Mia, and Lily are working on a project in their electronics lab. They are measuring the drain current (ID) for different voltage values between the gate and the source (VGS). Can you help them understand the purpose of this experiment?

• To determine the pinch-off voltage (VP)

• To measure the drain current with VGS = 0 (IDSS)

• To explore the linear part of the ID(VDS) characteristics

• To test the JFET as a constant current source

Daniel is working on a project where he needs to use a JFET as a constant current source. He is unsure about the range of load resistor values he should use. Can you help him understand the range of load resistor values that allows the JFET to function as a constant current source?

• 100 Ω - 100 kΩ

• 1 kΩ - 10 kΩ

• 10 kΩ - 100 kΩ

• 100 kΩ - 1 MΩ

Isla is working on a project where she needs to use a JFET current source with self-biasing. Samuel asks her, what is the advantage of using it?

• Zoe suggests that different current values can be obtained by adjusting the resistor R

• Samuel thinks it provides a constant voltage equivalent to a Zener diode

• Isla believes it allows for better control of the load resistor values

• Another student thinks it eliminates the need for a load resistor

Michael is working on a project involving a JFET transistor. He is observing the ID vs. VDS characteristics in its linear part. He notices that the current through the transistor is proportional to what?

• The voltage across it

• The gate voltage

• The resistance of the load resistor

• The frequency of the input signal

Aiden, Samuel, and Abigail are working on a project to improve the version of the two resistor voltage divider. They are considering adding a compensation circuit. What would be the purpose of this?

• To adjust the divider ratio

• To improve the linearity of the circuit

• To increase the output voltage

• To reduce the input voltage

In Lab 1, Zoe, Avery, and Harper are working on a project to understand the behavior of a Junction Field Effect Transistor (JFET). They decide to measure the drain current (ID) for different voltage values between the gate and the source (VGS). What is the purpose of this experiment?

• To determine the pinch-off voltage (VP)

• To measure the drain current with VGS = 0 (IDSS)

• To explore the linear part of the ID(VDS) characteristics

• To test the JFET as a constant current source

Aria, Priya, and Kai are working on a project involving a JFET current source with self-biasing. They are discussing the advantages of using it. Aria suggests that one of the advantages could be:

• Different current values can be obtained by adjusting the resistor R

• It provides a constant voltage equivalent to a Zener diode

• It allows for better control of the load resistor values

• It eliminates the need for a load resistor
