Question: A coil of 100 turns carries a current of 5 mA and creates a magnetic flux of 10?5 weber. the inductance is [Orissa JEE 2002]
Options:
A) 0.2 mH
B) 2.0 mH
C) 0.02 mH
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ {\varphi_{T}}=Li\Rightarrow L=\frac{{{10}^{-5}}}{5\times {{10}^{-3}}}=2mH $
