Which equations are called Maxwell's equations?

The source of displacement current is . . . . . . .

The voltage between the plates of a parallel plate capacitor of capacity $1 \ \mu F$ is changing at the rate of $4 \ V/s$. The displacement current in the capacitor is: (in $\mu A$)

Derive the expression for the displacement current term in the modified Ampere's circuital law. Define displacement current and state its $SI$ unit.

$A$ displacement current of $4.0 \text{ A}$ can be set up in the space between two parallel plates of a $6 \text{ }\mu\text{F}$ capacitor. The rate of change of potential difference across the plates of the capacitor is nearly $\alpha \times 10^6 \text{ V/s}$. The value of $\alpha$ is . . . . . . .

Seawater at a frequency $f = 9 \times 10^{2} \, Hz$ has permittivity $\varepsilon = 80 \varepsilon_{0}$ and resistivity $\rho = 0.25 \, \Omega m$. Imagine a parallel plate capacitor is immersed in seawater and is driven by an alternating voltage source $V(t) = V_{0} \sin(2 \pi ft)$. Then the conduction current density becomes $10^{x}$ times the displacement current density after time $t = \frac{1}{800} \, s$. The value of $x$ is ......... . $\left(\frac{1}{4 \pi \varepsilon_{0}} = 9 \times 10^{9} \, Nm^{2} C^{-2}\right)$
