Question:

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 :

Options:

ML2T–2 

ML2T–1I–1

ML2T–3I–2

ML2T–3I–1

Correct Answer:

ML2T–3I–2

Explanation:

Resistance : R = \(\frac{V}{I} = \frac{[ML^2T^{-3}I^{-1}]}{[I]}\)
