Question
The current through a 4.6 H inductor is shown in the following graph. The induced emf during the time interval t = 5 milli-sec to 6 milli-sec will be
- 103 V
- – 23 '103 V
- 23 ' 103 V
- Zero
The correct answer is: 23 ´ 103 V
Rate of decay of current between t = 5 ms to 6 ms
Hence induced emf
