Question

Write the dimensions of self-inductance.

(a) [M^3 L^2 T^-2 A^-2]

(b) [M L^2 T^-2 A^-2]

(c) [M^2 L^2 T^-2 A^-2]

(d) [M L^2 T^2 A^-2]

I have been asked this question in an interview.

My query is from Electromagnetic Inductance in division Electromagnetic Induction of Physics – Class 12

Answer 1

Correct answer is (b) [M L^2 T^-2 A^-2]

Explanation: Self-inductance = \(\frac {Magnetic \, flux}{Current}\)

\(\frac {[ M L^2 T^{-2} ]}{[ A^2 ]}\)

Self-inductance = [M L^2 T^-2 A^-2]
