A) \[2\times {{10}^{-3}}H\]
B) \[1\times {{10}^{3}}H\]
C) \[4\times {{10}^{3}}H\]
D) \[1\times {{10}^{-3}}H\]
Correct Answer: A
Solution :
Here: Current \[i=1\text{ }A\] Time t = 1 milli-sec \[=1\times {{10}^{-3}}sec\] The self inductance of the coil is given by \[L=\frac{2t}{i}=\frac{2\times {{10}^{-3}}}{1}\] \[=2\times {{10}^{-3}}H\]You need to login to perform this action.
