SECTION -B
How does Ampere-Maxwell law explain the flow of current through a capacitor when it is being charged by a battery? Write the expression for the displacement current in terms of the rate of change of electric flux.
Solution:
When a battery is attached to a capacitor, conduction current flow in wire outside capacitor. In the capacitor the Electric flux ϕ E = E A
Where,E =
, Q = ε 0 E A
∴I =
= ε 0
This maintains the current in the capacitor.
Amperes-Maxwell law states that displacement current comes into existence due to rate of change of electric flux w.r.t. time.
∴ I d = ε 0
Where,
∴
This maintains the current in the capacitor.
Amperes-Maxwell law states that displacement current comes into existence due to rate of change of electric flux w.r.t. time.
