What will be the self inductance of a coil of 100 turns if a current of 5 A produces a magnetic flux \(5 \times 10^{-5} \mathrm{~Wb}\) ?
- A \(1 \mathrm{mH}\)
- B \(10 \mathrm{mH}\)
- C \(1 \mu \mathrm{H}\)
- D \(10 \mu \mathrm{H}\)
Answer & Solution
Correct Answer
(A) \(1 \mathrm{mH}\)
Step-by-step Solution
Detailed explanation
Self inductance \(L=\frac{N \phi}{I}\)
\(
L=\frac{100 \times 5 \times 10^{-5}}{5}=10^{-3} \mathrm{H}
\)
\(
L=\frac{100 \times 5 \times 10^{-5}}{5}=10^{-3} \mathrm{H}
\)
