Challenge Problems
Push your limits with advanced challenges
A transformer has a copper resistance of 0.2 ohms and carries a primary current of 20 A. Calculate the copper loss and discuss its implications on overall efficiency.
💡 Hint: Use the loss formula to get the calculated loss and think about how that affects total power needed.
Discuss how transforming the core material from iron to an iron-silicon alloy could reduce hysteresis losses in a practical transformer application.
💡 Hint: Think about the properties of materials and friction in cycles.
