The momentum in mechanics is expressed as m×vm \times v. The analogous expression in electricity is

A

I×QI \times Q

B

I×VI \times V

C

L×IL \times I

D

3.75×10−2N3.75 \times 10^{- 2}N

Answer

L×IL \times I

Explanation

Solution

Magnetic flux φ=LI\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 φ=LI\varphi = LIis equivalent to momentum p=m×vp = m \times v.
