A quantity X is given by `in_(0) L(DeltaV)/(Delta t)`, where `in_(0)` is the permittivity of free space, L is a length, `DeltaV` is a potential difference and `Delta t` 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

`in_(0) L (DeltaV)/(Deltat)=[M^(-1)L^(-3)T^(4)I^(2)][L] ([M^(1)L^(2)T^(-3)I^(-1)])/([T^(1)])=[I]`
