Q26 · Physics
A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is :
- 1zero at all places
- 2constant between the plates and zero outside the plates
- 3non-zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the platesOfficial answer
- 4zero between the plates and non-zero outside
Official answer: option 3 · NTA final answer key
