Q102 / 200 · NEET 2007 · Physics

Dimensions of resistance in an electrical circuit, in terms of dimension of mass $M$, of length $L$, of time $T$ and of current $I$, would be

  • A
    $M L^2 T^{-2}$
  • B
    $M L^2 T^{-1} I^{-1}$
  • Correct answer
    C
    $M L^2 T^{-3} I^{-2}$
  • D
    $M L^2 T^{-3} I^{-1}$

Solution

We know that $\begin{aligned} R & =\frac{V}{I}=\frac{\left[M L^2 T^{-2}\right]}{\left[I^2 T\right]} \\ & =\left[M L^2 T^{-3} I^{-2}\right] \end{aligned}$

Hence, the correct answer is option: 'C'.
