I is conduction current

bro… aku rasa.. we have a contradictory situation that arises from the discontinuity of the current! lah

+ ???

ha’ah lah..but I think, Maxwell already solved this problem by postulating an additional term on the right side of Ampère’s law… ermmm…

yes…agreed he includes a factor called the

displacement current defined as

so.. must be the electric flux through the surface bounded by the path of integration

yes…agreed he includes a factor called the

so.. must be the electric flux through the surface bounded by the path of integration

then we can express the general form of Ampère’s law as

ладно, я понимаю, its also called as the Ampère–Maxwell law, kan?

wait… wait… why “maxwell” current called as displacement current, ha…?

wait… wait… why “maxwell” current called as displacement current, ha…?

halaah.. .relax bro, displacement in this context does not have the meaning lah…

the word is historically entrenched in the language of physics, so “sajer jer" we continue to use it…

the word is historically entrenched in the language of physics, so “sajer jer" we continue to use it…

anyway…how to understand the meaning of the expression by the Ampère–Maxwell law yer?

ooo… macam ni..tengok gambar ni! as Adam mentioned, the electric flux through S

Hence, the displacement current through S is

Hence, the displacement current through S is

Subhanalloh… meanings that the displacement current Id through S is precisely equal to the conduction current I in the wires connected to the capacitor!

so kalo macam itu, we can write all Maxwell’s equations lah to represent the laws of electricity and magnetism,

o..tadok-lah susah sangat, macam dah kenal semua jer,

only the last-one a bit change… perasan tak?

but I think, this is the simplified of Maxwell’s equations as applied to free space lah.. that is, in the absence of any dielectric or magnetic material… iya kan?

i think so… because, and are permittivity and permeability

fro free space

polarization!oscillation of the vector electric field (measured at a fixed point of space)

• EM waves are periodic changes of electric and magnetic fields in space and time

• They propagate at the speed of light • Magnetic field is always perpendicular to the electric field • Both the electric and magnetic fields oscillate in a plane perpendicular

to the direction of propagation of the light beam.
