Which of the following is not a unit of permeability
- A Henry meter-1
- B Weber ampere \({ }^{-1}\) meter \(^{-1}\)
- C Ohm second meter \({ }^{-1}\)
- D Volt second meter \({ }^{-1}\)
Answer & Solution
Correct Answer
(D) Volt second meter \({ }^{-1}\)
Step-by-step Solution
Detailed explanation
Self inductance, \(\mathrm{L}=\frac{\mu_0 \mathrm{~N}^2 \mathrm{~A}}{1}\) \(\therefore \quad\) Unit of \(\mu_{\mathrm{o}}=\frac{\mathrm{H} \cdot \mathrm{m}}{\mathrm{m}^2}=\mathrm{H} \mathrm{m}^{-1}\) Also, \(\mathrm{L}=\frac{\phi}{\mathrm{I}}=\mathrm{WbA}^{-1}\)…
