### Current when capacitor and resistor placed in parallel?

If the question is too long please comment to shorten it atleast , I really need an answer. I have just started learning about RC circuits and these circuits are confusing me.My questions-1)What will ...

### Conduction current for parallel-plate capacitor

I am reading Sadiku's Elements of Electromagnetics and here is the proof given to show that conduction current = displacement current for parallel-plate capacitor. Displacement current: \begin{align*}...

### Is the Lorentz transform of a bound current - a bound current?

The bound (magnetization) current is $\mathbf{J}_\mathrm{M} = \nabla \times \mathbf{M}$. The charge density of a moving magnet that is electrically neutral in its own rest frame satisfies the ...

### Is there Electric Flux through a closed loop around a current wire?

In one of his lectures, Professor Walter Lewin is ammending Ampère's Law to include displacement current (i.e. It not only depends on the current that penetrates the loop, but also on the changing ...

### Displacement Current Density of a parallel plate capacitor

Been stuck on this for a while and haven't been able to make sense of it. So let's say that we have a parallel plate capacitor with plate area, $A$, charging at a rate $i$. The gap between the plates ...

### Does a Changing Electric Field Between The Plates of a Charging Capacitor Really Create a Magnetic Field?

Maxwell asserted that a virtual current. the displacement current, which was proportional to the charging field between the plates was sufficient to produce a magnetic field of the same orientation as ...

### Displacement current in charging capacitor [duplicate]

In the classic example of a charging capacitor I can see how an Amperian loop with a surface going between the capacitor's plates would feel a changing electric flux, as the electric field between the ...

### Physical Interpretation of AMPERE's law [closed]

since we can get the charge conservation from ampere's law i was wondering is this the only physical interpretation of ampere's law ,what can be the more physical interpretations of ampere's law both ...

### Galvanic cell of zinc half cell and copper half cell

Where do the $Zn^{+2}$ ions come from in a $Zn$-half cell, if from zinc metal then why doesn't after some time $Zn$ metal is completely vanished and what is the purpose of $Zn^{+2}$ ions of zinc ...

### Maxwell's equations

In Jaynes' Probability Theory, he states: There are many more analogies. In physics we are accustomed to finding that any advance in knowledge leads to consequences of great practical value, but of ...

### displacement current

1)Is the sum of conduction and displacement current constant? 2)And is it possible to get a displacement current in a DC circuit? Is it right to say: Displacement current only exists when there is a ...

### What is the difference between free current and displacement current?

So the displacement current is introduced to make Ampere's Law consistent with time-dependent currents, and then becomes $$\oint \vec{B}d\vec{l}=\mu_0(I+I_d).$$ I am struggling to understand exactly ...
