Question: Which of the following is a characteristic of a JFET?

Options:

  1. It is voltage-controlled
  2. It is current-controlled
  3. It has a gate current
  4. It operates in the saturation region only

Correct Answer: It is voltage-controlled

Solution: 

A JFET (Junction Field Effect Transistor) is a voltage-controlled device, meaning the output current is controlled by the voltage applied to the gate.

Questions & Step-by-Step Solutions

Which of the following is a characteristic of a JFET?
  • Step 1: Understand what a JFET is. A JFET stands for Junction Field Effect Transistor.
  • Step 2: Learn that a JFET is a type of transistor used to control electrical signals.
  • Step 3: Know that it is a voltage-controlled device, which means it uses voltage to control the flow of current.
  • Step 4: Realize that the gate of the JFET is where the voltage is applied to control the output current.
  • Step 5: Conclude that the main characteristic of a JFET is that the output current is controlled by the voltage at the gate.
