Questions
What are the dimensions of electrical resistance?
a
ML2T−2A2
b
ML2T−3A−2
c
ML2T−3A2
d
ML2T−2A−2
detailed solution
Correct option is B
From Ohm's law, resistance R is given by R= potential difference current ∴ Dimensions of R=ML2T−3A−1A=ML2T−3A−2Thus, the correct choice is (2).Talk to our academic expert!
