A quantity X is given by `epsi_(0)L(DeltaV)/(DeltaT)` where `epsi_(0)` is the permittivity of the free space, L is a length `Delta`V is a potential difference nad `Deltat` is a time interval. The dimensional formula for X is the same as that of

Options

A. resistance
B. charge
C. voltage
D. current

Answer

D

Explanation

`X=in_(0)Lxx(DeltaV)/(Deltat)=(M^(-1)L^(-3)T^(4)A^(2))(L)((ML^(2)T^(-3)A^(-1)))/T" "=[M^(@)L^(@)T^(@)A^(1)]=` current
