If x=(epsilon(0)lV)/(t) where epsilon(0)...

If `x=(epsilon_(0)lV)/(t)` where `epsilon_(0)` is permittivity of free space, `l` is the length, `V` is the potential difference and `t` is the time, then dimensions of `x` are the same as that of :

A

resistance

B

Charge

C

voltage

D

current

Text Solution

Verified by Experts

The correct Answer is:
D
Here`x=in_(0)L(DeltaV)/(Deltat)=(qxxL)/(4piExxr^(2))xx(DeltaV)/(Deltat)`
`=(q)/(Deltat)xxLxx(DeltaV)/(DeltaV)xx(Deltax)/(L^(2))=(q)/(Deltat)=` current.
Hence correct choice is `(d).
