Answer PaperPaper Code: 183BQMaximum Marks: 60Time: 3 Hours

Part-A is a compulsory question which consists of ten sub-questions from all units carrying equal marks. Part-B consists of ten questions (numbered from 2 to 11) carrying 10 marks each. From each unit, there are two questions and the student should answer one of them. Hence, the student should answer five questions from Part-B.

Part A

Answer all sub-questions:

10 marks

What is the purpose of Dot convention?

1 marks

Answer

The dot convention is used to indicate the relative polarity of the induced voltages in coupled coils, allowing for the correct determination of the sign of mutual inductance in circuit equations.
