Verified Answer
What is the Poynting vector at the surface of a long cylindrical wire ...
The rate of flowing energy per unit area along a plane perpendicular to the direction of the wave motion is called Poynting vector denoted by letter S and is given as
Thus, Poynting vector 
Curved surface area of its cylinder = 2πrL
