A) \[-1H\]
B) \[-\frac{5}{4}H\]
C) \[-\frac{4}{5}\]
D) \[-\frac{2}{5}H\]
Correct Answer: A
Solution :
Here: Current i = 10 amp Time \[t=1\text{ }sec\] emf \[E=10\text{ }volt\] From the induced emf is given by \[E=-L\left( \frac{i}{t} \right)\] Or \[10=-K\left( \frac{10}{1} \right)\] Or \[L=-\frac{10}{10}=-1H\]You need to login to perform this action.
