The SI unit of inductance, the henry can be written as :

Options

A. weber/ampere
B. volt-second/ampere
C. `"joule/(ampere)"^(2)`
D. ohm-second

Answer

B

Explanation

`U=(1)/(2)Li^(2),[L]=[(U)/(i^(2))]`
and `L=(e)/(di//dt)`
`L=phi_(B)//i`
`rArr" "[L]=[phi//i][L]=[edt//di]=("volt-second")/("ampere")`
