What is conduction used for?
Conduction allows energy to travel through a medium. Some of its practical uses are making electricity flow in wires, cooking food, telephone conversations and conducting heat through the atmosphere to warm the earth.Another AnswerFurther to the original answer, energy doesn't travel through wires. A conductor allows the drift of current.
How can you create a volt?
you create a volt by conecting all to wires
What is it called when copper is pulled into thin wires?
Copper Wire
Why sulfur cannot be used to make wires?
As a nonmetal it does not conduct electricity and is not ductile.
What stops you from getting electrocuted?
Most often, the habit of staying away from live wires.
Why telephone line has negative voltage?
A negative live voltage is used to prevent electroytic corrosion on the copper wires.
How telephone wires connected?
I'll take that as "How are telephone wires connected?" but it's still unclear what you want to know. Telephone wires are connected just as any other wires are connected. By screw connections, by soldering, by crimping.
Why is copper used for telephone wires?
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Why do telephone wires become loose and sag in winter?
They shouldn't, usually it is the other way around. As with all wire, the temperature effects wire lengths. When wires become warm as in a hot summer day the wires expand and droop and likewise when they become cold as in winter they contract and tighten up. The wires have to be installed to take this condition into consideration. There is a specific engineered sag allowed for each type of conductor from pole fix point to pole fix point.
What will happen to the telephone lines if they are fitted tightly from pole to pole?
When a pole shifts with the earth it will pull the wires apart and cause a break somewhere in the line. The poles are meant to suspend the wires in air, not to stretch them... Accurate answer is the lines will break. While breaking is not normally due to poles shifting, that could happen. The reason the wires are slung loosely is because of the expansion and contraction properties of the metal wires. If you look at the lines in the winter, they do not sag much (are tighter) and in the summer the sag is pronounced (looser). If they were strung tightly, they would eventually break during the cold weather.
Why do telephone wires in warm weather slack?
All materials expand with temperature increases. This expansion in the metals and plastics of phone lines would cause them to lengthen, and thus go slack.
What do the telephone wire look like on a hot day?

Where are the telephone wires in big nate?
it is nere the pole
What do squirrels balance on telephone wires like?

When outside what do you do during earthquake?
make sure your not near any electrical wires or telephone wires
What are telephone wires made of?
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
What Can you do to prevent yourself from being struck by a lightning bolt?
Remain in your home during stormy weather. If you are outside of your home, avoid places that have high towers, fences with wires,trees.
