2. 2.

   What is the primary function of a transformer?

   Hint

   Think about the role of voltage in electrical systems.

3. 3.

   What is the primary role of a transformer in high-power circuits?

   • To step up voltage
   • To convert DC to AC
   • To store energy

   Hint

   Think about what aspect of voltage they manage.

4. 4.

   True or False: IGBTs are used primarily for applications requiring low power.

   • True
   • False

   Hint

   Consider the context of their use.

5. 5.

   You are designing a high-power circuit. Explain how you would select a transformer for efficient power transmission while minimizing losses.

   Hint

   Think about the longest distance for energy transfer.

6. 6.

   Given a circuit with a maximum current of 10A and a voltage of 120V, determine the appropriate specifications for a fuse to ensure safety.

   Hint

   Consider typical safety margins for fuse selection.
