Electrical Wiring

There are two types of electricity; dynamic and static electricity. The main difference between these two types is that in static electricity, the electrons do not move but in dynamic electricity, the electrons move either in changing directions or in one direction.

Mixing pigments is subtractive. Mixing light is additive. Let's take the primary pigments, red, blue and yellow. Red pigment is red because the chemical it is made of absorbs (subtracts) blue and yellow light that falls on it and reflects only red light to your eye. Similarly, blue pigment is blue because it absorbs red and yellow light and reflects only blue.

So when you mix the three primary pigments together, you produce something that absorbs all of the light falling on it in equal amounts and reflects nothing to your eye. Thus, it appears black.

In contrast, when you mix only red and blue light, there isn't any yellow in it, so the resulting light appears purple (the complement of yellow). Likewise, if you mix red and yellow light it appears orange (the complement of blue). If you mix all three colors of light together (in equal amounts), the resulting light appears white because it contains all of the "colors" of the spectrum. This explanation is sound, although greatly simplified.

Sky Becker is not cool like mohamad : )

Light, fiber optic or otherwise does not disappear. It travels and keeps on traveling until something stops it. point a fiber optic into the sky and it goes until it is stopped by something. The question, "How long does fiber optic light last for" has only one answer, forever.

Sulfur hexafluoride is an example of a gas commonly used as an insulator in high-voltage electrical equipment due to its excellent insulating properties and high dielectric strength.

Conductors and insulators are different and simalar in many ways.Two ways they are simallar are they both have electrons and have something to do with electricity.Three ways they are different that conductors let heat and electricity go through it .On the other hand insulators do not let heat or electreicity go through it easily.Another way is conductors transfer eelectrons easily but meanwhile the insulator psses on electrons with difficulty.One last thing is that conductors are not current but insulators are current.

Yes, silver nitrate in a solid state does not conduct electricity because it is an ionic compound. However, when dissolved in water, silver nitrate dissociates into silver ions (Ag+) and nitrate ions (NO3-), allowing it to conduct electricity as an electrolyte.

There are many materials that are used to insulate.

If the idea is to keep sound energy from entering a building steel springs, or rubber blocks, can be placed between a mechanical device and the building structure, or a fiber type insulation can be placed inside an air duct to keep the sound of the air in motion from being transferred to the building. Cloth sections are placed between metal duct work and a large centrifugal fan to stop sound transfer and/or vibrations from being transferred to the duct.

Porcelain or specially formulated epoxies are used to insulate high voltages from the ground. Special plastic or rubber-like material is used to insulate electrical wires.

Fiberglass bats, closed cell foam, cork, or even ground up paper are used for thermal insulation.

Almost any solid material, flexible or rigid, can be used to insulate from light.

"White" in US, Canada and countries with similar 60 Hz systems. "Blue" in Europe and countries with similar 50Hz systems. (However "Black" is also commonly installed in UK but this is part of obsolete wiring regulations/wiring code.)

It is called Double Insulated because any "hot" wires (= "live" wires in British English) inside the appliance have been made safe by using extra insulation and/or fuses to protect the user from getting a shock if the appliance suffers any damage. That is why it does not need a separate earth or ground wire. Always be sure to switch off the breakers at the main panel before you attempt to do any work on any mains power circuit.

The resistance value of gold is very low, typically around 22 microohms at room temperature. Gold is an excellent conductor of electricity due to its low resistance, which makes it useful in electronic components where low resistance is important.

Copper, for example.

Basically all metals.

The relationship between amperage and capacitance is indirect. Capacitance stores and releases electrical energy, affecting the flow of current in a circuit. Higher capacitance can lead to slower changes in current (i.e., lower frequency), while lower capacitance can result in faster changes in current.

The gas in the fluorescent tube has a high resistance when not lit, so it takes a high voltage to start it glowing. The "starter" stores energy and releases it all at once, causing a high voltage. Once the tube is glowing its resistance is lower, so it can continue to run without the starter. In fact the mains voltage is much higher than the tube requires to run once the gas inside it has been "lit" by the starter. A special thing called a "ballast" is included in the lamp fitting to reduce the mains voltage to one that is sufficient for the lamp to run continuously without overheating. If there was no ballast in the circuit supplying the lamp, the tube could get hot enough to explode!

Short Answer:

Salt water does conduct electricity. This is true of all types of salt solutions.

Explanation:

The electrical conductivity of water, both pure water and water with dissolved salts, is simpler to measure than to explain. Conductivity of water does not work like conductivity in a metal. In a metal, the outer electrons of the metal atoms are not tightly bound to specific atoms but rather distributed widely and are pretty much free to move in response to an electric field. When you apply a voltage to a metal you get a large flow of electrons.

In water, the application of a voltage results in the movement of charge, but the charges are not nearly-free electrons but rather ions (charged atoms or molecules). In pure water, the ions that are moving are the protons in the form of H3O+ and hydroxide ions, OH-. In other ionic solutions it is the dissolved ions themselves, for instance in salt water, sodium chloride dissociated into the ions Na+ and Cl-. The same works for other salts.

In some way, the conductivity of an ionic solution is easy to explain. When a voltage is applied, there develops an electric field. Any atom or molecule that has a net charge, q, feel a force, F=qE. Positive ions move in the direction of the field and negative ions move in the opposite direction. Both sets of moving charges add to make a current flows that in the direction of the field.

Of course, one expects that dragging an atom or molecule through a liquid is a lot harder than moving an election through a metal and thus one is not surprised that the conductivity due to ion motion is small. Sea water conducts electric current about a million times better than pure water and drinking water varies depending on the source, but might be a hundred to a thousand time more conductive than pure water. A metal, like gold, copper, aluminum will be a million times better than seawater at conducting electricity while an insulator like glass or rubber is a million times worse than pure water.

The energy delivered to a light bulb in a closed circuit with a battery comes from the chemical reactions happening inside the battery. These reactions create an electric current that flows through the circuit and powers the light bulb.

An acidic hydrogen atom is a hydrogen atom that has lost its electron and is running around as a hydrogen ion. The lone proton (in 1H) has loaned out its electron in a chemical reaction, like to chlorine in HCl, and when HCl is combined with water, the H and the Cl separate into H+ and Cl- ions. That H+ ion is the acidic hydrogen atom.

To transmit an 8 by 10 inch image over an ISDN B channel with 300 pixels per inch and 4 bits per pixel, calculate the total number of pixels in the image: 8 (inches) * 300 (pixels/inch) * 10 (inches) * 300 (pixels/inch) = 7,200,000 pixels. With 4 bits per pixel, the total number of bits required would be 7,200,000 * 4 = 28,800,000 bits. Convert this to bytes by dividing by 8, giving us 3,600,000 bytes or approximately 3.43 MB for transmission.

When talking of heating elements in the electrical trade the unit of watts is used. The higher the wattage value of the device the higher its temperature output. Heating cables are measured in watts per foot as a way of measuring their heat output. The equation to find wattage of a device is to multiply the voltage of the device times the amperage of the device as stated on the device's nameplate or tag.

In most cases the temperature is linear throughout the length of the heating element. The actual temperature can be tested by using a laser spot temperature test instrument.

The rubbed balloon becomes negatively charged from the transfer of electrons. The wooden wall becomes positively charged because it loses some electrons to the balloon. Opposite charges attract, causing the balloon to stick to the wall.

Electric charges can build up on an object when there is an imbalance of positive and negative charges. This imbalance can occur through friction, induction, or contact with other charged objects. When charges can't easily flow away, they accumulate and can create static electricity.

The least usable form of energy is thermal energy, such as low-temperature heat, because it is difficult to harness efficiently and convert into other forms of energy. Thermal energy is often dispersed and not easily concentrated or converted into useful work.

One simple way to demonstrate conduction by putting one end of a spoon directly above a flame. Heat will soon spread to the fingers of the person holding the spoon. Next , test other type of metals with varying lengths on the flame and have the participants determine how long it takes for heat to travel on different metals.
