Question

explain the energy transport and poynting vector ​

Answer 1

as the energy flux density (energy per unit area per unit time) and it is known as the Poynting vector (it 'Poynts' in the direction of energy transport). ... Thus the Poynting vector represents the flow of energy in the same way that the current J represents the flow of charge.

Answer 2

$\huge\fbox\pink{Answer}$

As the energy flux density (energy per unit area per unit time) and it is known as the Poynting vector (it 'Poynts' in the direction of energy transport).

Thus the Poynting vector represents the flow of energy in the same way that the current J represents the flow of charge.
