A quantity x is given by espilon_(0)L(DeltaV)/(Deltat) where espilon_(0) is permittivity of free space L is length, DeltaV is a potential difference and Deltat is the time interval. The dimensional formula for x is the same as that of :

Answer»

resistance
Charge
voltage
current

Solution :`epsilon_(0)L(DeltaV)/(Deltat)=C(DeltaV)/(Deltat)( :.epsilon_(0)L="capacity")`
`=(q)/(V)xx(DeltaV)/(Deltat)=(q)/(Deltat)( :.C=(epsilon_(0)A)/(d))`
Current.
HENCE correct choice is `(d)`.
