Question

a quantity `X` is given by `epsilon_(0)L(DeltaV)/(Deltat)` where `in_(0)` is the permittivity of the free space, L is a length, `DeltaV` is a potential difference and `Deltat` is a time interval. The dimensinal formula for `X` is the same as that of
A. resistance
B. charge
C. voltage
D. current

Answer 1

Correct Answer - D
`because[epsi_(0)L]=["Capacitantce C"]`
`thereforeepsi_(0)L(DeltaV)/(Deltat)=(CDeltaV)/(Deltat)=(Deltaq)/(Deltat)=("Charge")/("time")=`current.
