A) \[1\,\,H\]
B) \[0.5\,\,H\]
C) \[1.5\,\,H\]
D) \[2\,\,H\]
Correct Answer: D
Solution :
From the formula,\[\varepsilon =-L\frac{dl}{dt}\] Take magnitude on both sides. \[|\varepsilon |\,\,=\left| -L\frac{dI}{dt} \right|\] or \[\varepsilon =L\frac{dI}{dt}\] \[\therefore \] \[80=L\left( \frac{2}{0.05} \right)\] \[\Rightarrow \] \[80=L\times 40\] \[\Rightarrow \] \[L=\frac{80}{40}\] \[\Rightarrow \] \[L=2H\]You need to login to perform this action.
