COMEDK · Physics · 22. Electromagnetic Induction
Select the unit of the coefficient of mutual induction from the following.
- A weber. ampere
- B volt. ampere / second
- C volt. second / ampere
- D ampere / weber
Answer & Solution
Correct Answer
(C) volt. second / ampere
Step-by-step Solution
Detailed explanation
The coefficient of mutual induction \(M\) is defined by the relation \(\phi = M I\), where \(\phi\) is the magnetic flux and \(I\) is the current. From this relation, \(M = \dfrac{\phi}{I}\). The unit of magnetic flux \(\phi\) is Weber (Wb) and the unit of current \(I\) is…
