What is the dimensional formula of potential difference

then W = F x L,

then Q = I x T

then Dimension for Force (F) is [M][L][T]

^{-2}

Dimention for Length (L) is [L]

Dimention for current Electric (I) is [ I ]

Dimention for Time (T) is [T]

so

V = W / Q = (F x L) / (I x T)

V = ([M][L][T]

^{-2}[L]) / ([ I ][T])

= [M][L]

^{2}[T]

^{-2}[ I ]

^{-1}[T]

^{-1}

= [M][L]

^{2}[T]

^{-3}[ I ]

^{-1}

Dimention for Voltage is [M][L]

^{2}[T]

^{-3}[ A ]

^{-1..A=I...(Current)}
