5.2.1. Structure and Operation

Try these first

1. 1.

   What are the three terminals of a MOSFET called?

   Hint

   Think about the control and flow of current.

2. 2.

   What does the Gate terminal do in a MOSFET?

   Hint

   Consider what role it plays in switching the MOSFET on or off.

3. 3.

   What does the Gate terminal of a MOSFET control?

   • Current flow
   • Device operation
   • Voltage output

   Hint

   Consider what aspect the Gate influences about the MOSFET.

4. 4.

   True or False: The Drain terminal is where current enters the MOSFET.

   • True
   • False

   Hint

   Remember the flow direction of current in the terminals.

5. 5.

   Analyze a circuit where a MOSFET is used to control an electric motor. Describe how changing the gate voltage affects motor speed and performance.

   Hint

   Consider the relationship between voltage, current, and motor performance.

6. 6.

   Design a simple switch using a MOSFET to control a light bulb. What parameters would you consider for the MOSFET selection?

   Hint

   Think about the light bulb’s ratings and how they relate to MOSFET specifications.
