NEET Solved Paper 2016 Question 42
Question: A long solenoid has 1000 turns. When a current of 4A flows through it, the magnetic flux linked with each turn of the solenoid is $ 4\times {10^{-3}},Wb\text{.} $ The self-inductance of the solenoid is :-
Options:
A) 4H
B) 3H
C) 2H
D) 1H
Show Answer
Answer:
Correct Answer: D
Solution:
- Flux linked with each turn $ =4\times {10^{-3}}Wb $
$ \therefore $ Total flux linked $ =1000[4\times {10^{-3}}]Wb $ $ o| _{ttotal},=4\Rightarrow Li=4\Rightarrow L=1H $
