If someone can explain why a capacitor blocks DC, but not AC, with some math, I will understand all of that much better. I know that there are picture animations illustrating this, but I really want ...

Capacitors behaving as an open circuits, How can we understand the concept of the Electrons flowing through a capacitors.

Kindly help me understand the difference between conduction current and displacement current. Quick searches explain that displacement current is associated with changing electric field, frankly ...

This question has been in my head for so many days. When I was studying BJT amplifiers, capacitors were used for blocking DC. It is called a coupling capacitor. When the AC signal is superimposed on ...

Can someone clarify whether or not a capacitor blocks current at DC? simulate this circuit – Schematic created using CircuitLab

What my professor is telling us that there is no conduction current through a parallel plate capacitor but the current that is passing through capacitor is the displacement current and this phenomena ...

I have here a filtering circuit from a microwave. What is the point of the capacitors to ground. Another answer in a previous question of mine said they were used for filtering however I don't ...

What does a series capacitor on a PCIe signal trace do, and how does it work? I've read that a series capacitor smooths out ripple in a power line, but this is a signal trace, and I'd like to know ...

The HPF attenuates frequencies which are below the cutoff frequency. But, in many cases a HPF is used to remove the DC level from any voltage. For example, in this case, the IC AD5933 supplies an ...

I have looked all over the interwebs for a few good hours now, and I cannot find anything that simply explains a capacitor! I know that the capacitance of a capacitor is measured in uF, but what is ...

Possible Duplicate: Basic Frequency Control Circuit In the following schematic, why can't R4 be taken away and the feedback network pass output feedback through C2 and R2?

If capacitors are connected in series with a vltg source, then how would each plates get the polarity? For a single capacitor, the electrons from one plate are pumped by the source towards the other ...

If I have a single metal plate, a battery, and one wire. If I connect the wire to the positive on the battery to the metal plate, does that remove electrons from the metal plate? I am attempting to ...

How does the electric field inside a charged capacitor force the electrons in a conductor to flow and establish electricity?
