Physics And Measurement Question 45
Question: If $ C $ and $ R $ represent capacitance and resistance respectively, then the dimensions of $ RC $ are
[CPMT 1981, 85; CBSE PMT 1992, 95; Pb. PMT 1999]
Options:
A) $ M^{0}L^{0}T^{2} $
B) $ M^{0}L^{0}T $
C) $ M{{L}^{-1}} $
D) None of the above
Show Answer
Answer:
Correct Answer: B
Solution:
$ RC=T $ ∵ $ [R]=[ML^{2}{{T}^{-3}}{{I}^{-2}}] $ and $ [C]=[{{M}^{-1}}{{L}^{-2}}T^{4}I^{2}] $
