1 Displacement Current This term must represent a current
This term is conduction current IC Application of Stokes’s theorem gives: Cont.

2 Displacement Current Define the displacement current as:
The displacement current does not involve real charges; it is an equivalent current that depends on

3 Capacitor Circuit I2 = I2c + I2d I2c = 0 (perfect dielectric)
Given: Wires are perfect conductors and capacitor insulator material is perfect dielectric. For Surface S2: I2 = I2c + I2d I2c = 0 (perfect dielectric) For Surface S1: I1 = I1c + I1d (D = 0 in perfect conductor) Conclusion: I1 = I2
