Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An auto-transformer has 100 turns in the primary and 250 turns in the secondary. If the primary voltage is 230V, calculate the secondary voltage and the efficiency if the copper losses are 50W and core losses are 20W.

💡 Hint: First calculate the secondary voltage before solving for efficiency using the losses.

Challenge 2 Hard

Discuss the impact of using an auto-transformer in a high-voltage application where electrical isolation is crucial.

💡 Hint: Consider specific safety regulations or standards in high-voltage environments.
