Electro Magnetic Induction And Alternating Currents Question 598
Question: A coil of N = 100 turns carries a current I = 5 A and creates a magnetic flux $ \varphi ={{10}^{-5}}T{{m}^{-2}} $ per turn. The value of its inductance L will be [UPSEAT 2004]
Options:
A) 0.05 mH
B) 0.10 mH
C) 0.15 mH
D) 0.20 mH
Show Answer
Answer:
Correct Answer: D
Solution:
$ N\varphi =Li $
$ \Rightarrow 100\times {{10}^{-5}}=L\times 5\Rightarrow L=0.2\ mH. $
