The dimensions of coefficient of self inductances are

Options

A. `[ML^(2)T^(-2)A^(-2)]`
B. `[ML^(2)T^(-2)A^(-1)]`
C. `[MLT^(-2)A^(-1)]`
D. `[MLT^(-2)A^(-1)]`

Answer

A

Explanation

Energy `U=1/2 Ll^(2)` where `L` is coefficient of selt induction
`[L]=([U])/([l]^(2))=([ML^(2)T^(-2)])/([A]^(2))`
`=[ML^(2)T^(-2)A^(-2)]`
