The dimensional formula of self-inductance is

View answer and explanation

Correct option: C

\left[ {\mathrm{M}{\mathrm{L}^2}{\mathrm{T}^{ - 2}}{\mathrm{A}^{ - 2}}} \right]

Option C (

\left[ {\mathrm{M}{\mathrm{L}^2}{\mathrm{T}^{ - 2}}{\mathrm{A}^{ - 2}}} \right]

) is correct because self-inductance is related to energy stored in a magnetic field, and its dimensions can be derived from that.
