Which of the following statements regarding an ideal single-phase transformer having a turn ratio of 1:2 and drawing a current of 10 A from a 200 V AC supply is incorrect?
Understand the Problem
The question is asking to identify the incorrect statement from a set of options regarding an ideal single-phase transformer with a specific turn ratio and current draw from an AC supply. It suggests an understanding of transformer principles and relationships between voltage, current, and turns ratio.
Answer
The secondary current being 5 A is incorrect.
The statement "Its secondary current is 5 A" is incorrect.
Answer for screen readers
The statement "Its secondary current is 5 A" is incorrect.
More Information
In an ideal transformer with a turns ratio of 1:2, the secondary voltage is doubled while the current is halved. With a primary current of 10 A, incorrect statements about the secondary current are common.
Tips
Common mistakes include misunderstanding transformer operation principles, such as assuming the secondary current is simply half of the primary without considering the full context of power conservation.
