Overhead electricity cables are not tightly strung over a pylon to account for factors like temperature changes, wind-induced movements, and maintenance needs. Having some slack in the cables helps to reduce stress on the wires and prevent damage or breakage.
There are losses in any machinery- friction of moving parts, loss of heat from steam, a turbine will only capture PART of the energy of the water or steam striking it, and generators do not convert ALL mechanical energy to electricity. There is also electrical resistance in the cables.
No, electricity moves at the speed of light, which is the fastest speed possible in the universe. Therefore, it is not possible for anything to move faster than electricity.
A solution that allows electricity to pass through it is called an electrolyte. This is because it contains ions which can conduct electricity.
To determine the maximum weight an overhead storage unit can hold, you should consult the manufacturer's specifications and guidelines. These will outline the weight capacity of the unit and any weight limitations. It is important to never exceed the recommended weight limit to avoid damaging the storage unit or causing a safety hazard.
Forcing a connection when attaching cables can result in damage to the connectors or the devices they are connecting. By aligning the connectors properly and allowing them to be inserted smoothly, you reduce the risk of bending or breaking the pins inside the connectors. Taking the time to make sure the connectors are properly aligned before making the connection is key to preventing damage.
i belive it because there not grounded ?
A power plant can supply a factory along cables or overhead lines. In that case the electric power produced from a primary fuel in the power plant has to travel along the cables to the factory. That is how electric power travels. A piece of theory by J.H.Poynting published in the 1890s showed that the power travels in the electric and magnetic fields surrounding the wires according to electromagnetic theory. This has never been demonstrated by experiment but it is entirely consistent with the laws of nature as expressed by J.C.Maxwell in his 'Treatise on Electricity and Magnetism' on which electrical theory and engineering is based.
The sun is never overhead at 42 degrees north.
It never is overhead at noon because Texas is not in the northernmost point where the sun passes directly overhead at noon.
Antarctica would never have the sun directly overhead at any time during the year due to its location near the South Pole. The tilt of Earth's axis ensures that the sun never reaches directly overhead in this region.
During warm weather the cable will expand and sag slightly. If the cable had then been put up too tightly, when the cold weather arrived, the cable would contract and could snap or damage the fastening that clip the cable to the poles.In other words, the sag is to allow for expansion and contraction of the cables.
A four wire cable is one that has four wires in it. Usually a red, black, blue and a white wire. When talking about cables the ground wire is never counted because now a days all cable sets have ground wires in them and are sized to the capacity of the cable's ampacity.
The sun is never directly overhead in Levittown, NY, as it lies above the Tropic of Cancer.
The answer to the riddle "What flies overhead but never on a string" is a kite, in the sense of a bird. Birds fly freely in the sky without being controlled by strings, unlike a kite that is flown with a string.
no and Never will be
no and Never will be
Never hear that term used .
