A) 3H
B) 1.67 H
C) 6 H
D) 0.67 H
Correct Answer: B
Solution :
\[{{I}_{1}}=5A\] \[{{I}_{2}}=2A\] \[\Delta I=2-5=-3A\] \[\Delta t=0.1\sec \] \[Emf=50v\] \[emf=\varepsilon =-L\frac{di}{dt}\] \[50=-L\left( \frac{-3}{0.1} \right)\] \[50=30L\] \[L=\frac{5}{3}=1.67H\]You need to login to perform this action.
