A) AC current
B) DC current
C) displacement current
D) impedance
Correct Answer: C
Solution :
Maxwell transformed Ampere?s law As curl \[\vec{B}={{\mu }_{0}}\left( \vec{J}+\frac{\delta \vec{D}}{\delta t} \right)\] The term\[\frac{\delta \vec{D}}{\delta t}\]is called displacement current density, since it arises when the electric displacement \[\text{\vec{D}}\]changes with time. Maxwell assumed that it is just as effective as \[\text{\vec{J}}\]in producing magnetic field. The introduction of displacement current is one Maxwell major contribution to the electromagnetic theory.You need to login to perform this action.
