A) 0.2 H
B) 0.5 H
C) 0.3 H
D) 0.4 H
E) 0.1 H
Correct Answer: B
Solution :
Given, \[e=1\,V,\]\[\frac{dI}{dt}=\frac{0.4-0.2}{0.1}\] \[\Rightarrow \] \[\frac{dI}{dt}=2A{{s}^{-1}}\] As, \[e=L\frac{dI}{dt}\] \[\Rightarrow \] \[L=\frac{e}{\frac{dI}{dt}}=\frac{1}{2}=0.5\,H\]You need to login to perform this action.
