`ML^(3) T^(-1) Q^(-2)` is dimension of

A

Resistivity

B

Conductivity

C

Resistance

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
(1) `V = iR`
`R = (V)/(i) : (j o u l e)/(c o u l . (c o u l//s))`
`[R] = (ML^(2) T^(-2) T)/(Q^(2)) = ML^(2) T^(-1) Q^(-2)`
Resistivity `R = (rho l)/(A)`
`rho = (RA)/(l) = [R] [L] = ML^(3) T^(-1) Q^(-2)`
