A parallel plate capacitor is being discharged. What is the direction of the energy flow in terms of the Poynting vector in the space between the plates?
  • a)
    Circumferential 
  • b)
    Radially inward 
  • c)
    Radially outward 
  • d)
    Along the wire in the positive z-axis
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A parallel plate capacitor is being discharged. What is the direction ...
As the capacitor is being discharged, field is decreasing
Using expression for curl in cylindrical coordinates, we get

Since there is φ symmetry

Thus, magnetic field in  direction will be induced, since,
∴ Direction of poynting vector 
 radially outward
The correct answer is: Radially outward
