   Hint

   Think about voltage adjustments.

2. 2.

   Which component is primarily used to control electrical energy flow?

   Hint

   These devices play a crucial role in energy control.

3. 3.

   What is the main role of power semiconductors in high-power circuits?

   • To convert AC to DC
   • To control energy flow
   • To store electrical energy

   Hint

   Think about the primary functions of energy management.

4. 4.

   True or False: Transformers are used only to step up voltage.

   • True
   • False

   Hint

   Consider the dual function of transformers.

5. 5.

   Design a simple circuit using a MOSFET and a transformer. Describe the component selection process, including criteria for voltage and current ratings.

   Hint

   Think about how you would match power requirements to component ratings.

6. 6.

   Explain the consequences of selecting a capacitor that is rated too low for a high-power circuit. Include potential impacts on efficiency and safety.

   Hint

   Consider what happens when a component is stressed beyond its design limits.
