Question

If $C$ and $R$ represent capacitance and resistance respectively, then the dimensions of $RC$ are –

• A. $M^{0}L^{0}T^{2}$
• B. $M^{0}L^{0}T$
• C. $ML^{- 1}$
• D. None of the above

Answer 1

Answer: (B)

$M^{0}L^{0}T$

Answer 2

$RC = T$

∵ $\lbrack R\rbrack = \lbrack ML^{2}T^{- 3}I^{- 2}\rbrack$ and $\lbrack C\rbrack = \lbrack M^{- 1}L^{- 2}T^{4}I^{2}\rbrack$
