A) 1 mH
B) 20 mH
C) 2 mH
D) 10 mH
Correct Answer: D
Solution :
(d) 10 mH Here \[\varepsilon =20mV=20\times {{10}^{-3}}V\] We know that, \[\left| \varepsilon \right|=M\frac{dl}{dt}\] \[\Rightarrow 20\times {{10}^{-3}}=M\left( \frac{6-2}{2} \right)\] \[20\times {{10}^{-3}}=M(2)\] \[\Rightarrow M=10\times {{10}^{-3}}H\] \[=10\,mH\]You need to login to perform this action.
