i) Dimention for Voltage is [M][L]2[T]-3[ I ]-1
ii) Joule and coulombs not SI units..because SI units using basic units of mks system
there are 7 basic quantity using SI units
Mass, Length , Time , Electric current, Temperature, Luminous Intensity, The amount of subtance. they are represented...
the formula for V is V = W / Q
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])...
