Electro Magnetic Induction And Alternating Currents Question 580
Question: If a change in current of 0.01 A in one coil produces a change in magnetic flux of $ 1.2\times {{10}^{-2}}Wb $ in the other coil, then the mutual inductance of the two coils in henries is [EAMCET 2001]
Options:
A) 0
B) 0.5
C) 1.2
D) 3
Show Answer
Answer:
Correct Answer: C
Solution:
$ \varphi =Mi\Rightarrow M=\frac{1.2\times {{10}^{-2}}}{0.01}=1.2H $
