Electrical Wiring

The static charges are held in the electrons

A solar cell will vary in length, width, and weight. Solar cells were first used in 1873 by an inventor named Charles Fritts.

Then those conduits may never come apart.

Impedance parameters or Z-parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering to describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small signals. They are members of a family of similar parameters used in electronics engineering, other examples being: S-parameters,[1] Y-parameters,[2] H-parameters, T-parameters or ABCD-parameters.[3][4]


The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the input currents, output voltages and the Z-parameter matrix is given by: .

For the general case of an n-port network, it can be stated that

William Gilbert was 56 years old when his work on magnetism was first published. He was born in May, 1544, and died in November, 1603.

Compact fluorescent light bulbs are cooler, use less electricity, and last a great deal longer than incandescents. However, they are more expensive than incandescent light bulbs and do contain trace amounts of mercury. They also have a slight delay before turning on.

The voltage for a potential relay will depend on the circuit that the relay is installed in. The relay can be made for low voltages (5v) to higher voltages (440.)

A negative KVAR reading can be eliminated by adding an inductor to the circuit.

Power hopefully is removed so the fire cannot get bigger.

China is a huge producer of a lot of items about 72% of everything you flip over and look at the bottom will say, 'Made in China' its not just electrical, but maybe it is because in u.s.a. a lot of people use electronics and we evolve around electronics, we depend on electronics, and if we are getting shipments from China possibly they want to make the most profit from us so the make electronics, and so when it ships they get more stuff, but i also have always wondered why everything was released in china first? xbox 360, ps3, Wii, etc...??

Yes. At normal temperatures copper conducts electricity better than almost any other metal; silver is slightly better.

Getting an electric shock can feel like a sudden intense jolt or tingling sensation that can be painful and startling. It may cause muscle contractions, numbness, or a burning sensation at the site of contact. The severity and duration of the shock experience can vary depending on factors such as the voltage and current of the electrical source.

This scenario did happen in the early 70's. Manufactures started making common home wiring from aluminum (AL). Because of the care that had to be taken when installing and splicing it only lasted for about five years. As copper became more plentiful general wiring swung back to copper wiring. Aluminium wiring is still used for service drops because of the cheaper cost of aluminium wire in bigger sizes over copper.

The property that allows certain metals to attract each other is called ferromagnetism. This occurs when the metal atoms have aligned magnetic moments that create a magnetic field, causing them to be attracted to each other. Materials like iron, nickel, and cobalt exhibit strong ferromagnetic properties.

The plastic is a form of insulation. Insulation used to be made from non-plastic materials like cloth. It protects the wire from the outside world. Without insulation the electricity would cause shocks, fires, and short circuits.

This abbreviation comes from the 1950s US Navy electrical shipyards assemblies.

It was used to abbreviate what was then called "Circuit Breakers".

This is how the "K" crawled in.

Today these parts are simply called connectors or headers but the abbreviation stuck since.

Many say that it is a mere spelling error, but the fact is that English abbreviations are often misspelled compared to their origin words, for example - OK abbreviates "All Correct".

The obvious answer is "only use what you absolutely need". Some specifics:

1. Anything electrical that produces heat is using a lot of power ... heaters, electric ranges, toasters and toaster ovens, microwave ovens, hair dryers, etc. ... use sensibly.

2. Anything electrical that produces cold is using a lot of power ... refrigerators and freezers have to start re-cooling the box every time you open the door ... also, "frost-free" appliances use far more power than the more efficient (and less expensive) old-style appliances that have to be manually defrosted. Dust that accumulates in the back or bottom of an appliance reduces its efficiency, so refrigerators and freezers need to have their working parts thoroughly cleaned at least once a year... Air conditioning is one of the largest power users in a home or business.

3. Old-style incandescent light bulbs (the ones that get really hot) are the most wasteful way of producing light. CFL's (compact fluorescent lamps) are now available to replace most incandescent lighting at reasonable prices ... LED lighting will be even more efficient, but the technology isn't yet mature enough for mainstream lighting needs.

4. The amount of electrical energy that you use depends on the time that you use it ... don't turn it on until you need it, turn it off when you're done.

5. If you have a lot of electronics equipment, much of it continues to use electricity even when it's turned "off" ... that's because it really doesn't go off, it goes into a state of "standby" ... All those little transformers (the small square boxes that plug into an outlet) continue to use electricity even when the equipment they supply is not being used ... plug all your electronics equipment into power strips or surge protector strips, and turn the strips off when you're not using the equipment ... when the strip is off, everything is really off.

6. Entire books have been written on the subject of conserving electricity ... visit a library.

Yes, the compass needle will change direction if the flow of electricity in the wire near it is reversed. This is because the flow of electricity creates a magnetic field around the wire, which can interact with the magnetic field of the compass needle.

I think that the best temperature for storing batteries is probably in a dry not-cold or not-hot room

Generally, electrical currents above 10 milliamperes can be dangerous for the human body, particularly if the current flows through the heart. Currents below this level are less likely to cause harm, but individual factors, such as the path the current takes through the body and the duration of exposure, can also affect safety.
