Physics And Measurement Question 63
Question: If $ L $ denotes the inductance of an inductor through which a current $ i $ is flowing, the dimensions of $ Li^{2} $ are
[CPMT 1982, 85, 87]
Options:
A) $ ML^{2}{{T}^{-2}} $
B) Not expressible in $ MLT $
C) $ ML{{T}^{-2}} $
D) $ M^{2}L^{2}{{T}^{-2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{1}{2}Li^{2} $ = Stored energy in an inductor = $ [ML^{2}{{T}^{-2}}] $
