Question

What is the dimensional formula of self-inductance?

विकल्प

• \[\mathrm{M\,L^{2}\,T^{-3}\,A^{-2}}\]

• \[\mathrm{M\,L^{-2}\,T^{-2}\,A^{-2}}\]

• \[\mathrm{M\,L^{2}\,T^{-2}\,A^{-2}}\]

• \[\mathrm{M\,L^{2}\,T^{-2}\,A^{-1}}\]

Answer 1

Self-inductance has units of \[\mathrm{V\,s\,A^{-1}}\]. Expressing those units in fundamental dimensions gives \[\mathrm{M\,L^{2}\,T^{-2}\,A^{-2}}\].
