the current is actually a result of many factors. depending on the voltage type (AC or DC) it could be as simple as resistance in the circuit. when you are talking about AC circuits, there are also capacitive reactance (Xc), inductive reactance Xl), resistance, variances in voltage (fluctuations) , frequency... also the "skin effect" must be taken into account. solid conductors(especially at higher frequencies), are susceptible to eddy currents within the conductor itself. meaning that current just circulates withing the center, forcing EMF (electromotive force) to the outer "skin" of the conductor.

In the electrical system of the US what is the difference between the neutral and the PE Ground?

US NEC: The neutral conductor is an insulated grounded conductor used as the current return in a circuit. The color designation for neutral is white. The protective ground (PE, protective - earth) is a non-insultated grounding conductor used to shunt fault current to ground, tripping the protective device. The color designation for PE ground is green. Neutral and PE ground are tied together at the distribution panel. PE ground is also connected to a solid earth ground, such as grounding rods driven into the earth. Downstream of the distribution panel, PE ground is never used to carry operational current. Any current flow on PE Ground, other than parasitic current, is considered a ground fault, which must be corrected. In fact, GFCI (Ground Fault Current Interrupting) breakers will trip when neutral current does not match hot current, an indication of PE ground current flow.


Why are AC and DC resistance different?

An AC current tends to flow towards the surface of a conductor due to a phenomenon called the 'skin effect', which acts to reduce the effective cross-sectional area of that conductor.Since resistance is directly-proportional to the cross-sectional area of a conductor, the conductor's resistance to an AC current is, therefore, higher than its resistance to a DC current (which distributes itself across the full cross-sectional area). We call this elevated value of resistance, AC resistance.The skin effect increases with frequency to such an extent that, at radio frequencies, there is little point in using solid conductors and tubes are used instead. At mains' frequencies (50/60 Hz), however, the skin effect is moderate and, so, the value of a conductor's AC resistance is only slightly elevated compared to its true resistance.It's important not to confuse the term 'AC resistance' with 'reactance', which is a function of a conductor's inductance and/or capacitance, and the frequency of the supply.


What is skin effect and methods to reduce skin effect?

with the inductance of a conductor it tends to push current flow to the outsideto reduce the effect you make the conductor hollowwith 80 hz and Cu conductor the current is in the outer 8mm or so.AnswerYou cannot really reduce the skin effect in ordinary conductors; for the sake of economy, you can use tubular conductors. Tubular conductors do not reduce the skin effect, but merely saves copper (if little current flows towards the centre, why have a centre!). However, special, insulated, conductors ('litz' wire) woven or braided in various patterns, can be used for special applications (e.g. high-frequency transformer windings) up to around 1 MHz or so. Because each strand has a very small cross-sectional area, and is insulated from its adjacent conductors, the skin effect is negligible compared with if it were a solid conductor.


How do you calculate diameter of a copper wire conductor and how do we calculate resistance of a copper wire conductor of a particaular length?

You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage

When does electricity flow through a solid electrical conductor?

Electricity flows through a solid electrical conductor when a potential difference (voltage) is applied across its ends, creating an electric field that drives the movement of electrons through the conductor. The flow of electrons constitutes an electric current, which is the movement of charge that powers electrical devices and systems.


What type of solid is likely to be the best conductor of an electric current?

A metal solid is likely to be the best conductor of an electric current due to its free electrons that can move easily through the material, allowing for efficient flow of electricity. Metals generally have high conductivity compared to other solid materials.


Why is a melted ionic compound is a good conductor of electric current but a solid ionic compound is a poor conductor of electric current?

Upon melting, the ions are free to move and conduct electricity.


What is the difference between a electrolytic conductor and a metallic conductor?

Electrolytic conductors conduct electricity through the movement of ions in a solution, while metallic conductors conduct electricity through the movement of electrons in a solid material. Electrolytic conductors are typically liquids or solutions, while metallic conductors are solid materials with freely moving electrons.


What is the advantage of using a stranded copper conductor over a solid copper conductor?

It would of course depend on the specific application. Current tends to travel on the surface of a conductor and a stranded conductor has more surface area and thus offers less resistance to the current. Stranded wire also bends a bit easier than the corresponding size solid wire.


Why is solid halite not a good electrical conductor?

Solid halite (salt) is made up of sodium and chloride ions that are tightly bound together in a crystalline structure. These strong ionic bonds prevent the movement of free electrons, which are necessary for electrical conduction. As a result, solid halite does not conduct electricity well.


Which substance meets the requirements cubic solid poor electrical conductor in the solid state good conductor when fused a sodium chloride b diamond c sulfur d chromium?

b Diamond - Diamond is a cubic solid that is a poor electrical conductor in the solid state due to its lack of free electrons. However, when diamond is fused, it can conduct electricity due to the movement of charged particles.


Is an iron nail a conductor?

Yes, it's a copper-colored solid


Difference between solid and stranded conductors?

Solid conductors are made of a single piece of metal wire and are rigid, making them suitable for permanent installations. Stranded conductors are made up of multiple thinner metal wires twisted together, providing flexibility and making them ideal for applications that require frequent bending or movement.


Is calcium chloride a good conductor of electricity?

Yes, calcium chloride is a good conductor of electricity when dissolved in water. The dissolved ions in calcium chloride allow the flow of electric current through the solution. However, solid calcium chloride is not a good conductor of electricity because it does not contain free-moving ions.


Is Solid sodium chloride is a good conductor of electric current?

No, solid sodium chloride is not a good conductor of electric current because it is an ionic compound. In the solid state, the ions are not free to move and carry electric charge, so it does not conduct electricity well.


What do you call solids that conduct electricity?

A substance that conducts electricity is a conductor. There is no special name for one that is solid; if you need to specify that it is solid, just call it a "solid conductor".
