Electro Magnetic Induction And Alternating Currents Question 528
Question: The momentum in mechanics is expressed as $ m\times v $ . The analogous expression in electricity is [MP PMT 2003]
Options:
A) $ I\times Q $
B) $ I\times V $
C) $ L\times I $
D) $ 3.75\times {{10}^{-2}},N $
Show Answer
Answer:
Correct Answer: C
Solution:
Magnetic flux $ \varphi =LI $ By analogy, since physical quantities mass (m) and linear velocity (v) are equivalent to electrical quantities inductance (L) and current (I) respectively. Thus magnetic flux $ \varphi =LI $ is equivalent to momentum $ p=m\times v $ .
