What element is used for wires that carry electricity?
Copper
What prevents electricity from leaking out of wires in a circuit?
Because electricity must be conducted in order to move. It is not a liquid.
What did railroads use to conduct electricity along railroad?
The early railroads established "polelines" to carry telegraph wires and electricity alongside the railroad tracks. These looked like what are called telephone poles today, but could have large "crossarms" at the top to carry many wires. These began with just 2 or 4 wires for telegrph use, which later had 2 wires for electricity added. As technology advanced, more wires were added to control trains and send other messages along the lines.
What is the purpose of using 3 different colour wires in an electric iron?
The live (blue) wire delivers the power from the mains into the iron's circuit. The neutral (brown) is the return path back to the mains (electricity needs a closed circuit to flow). The earth (green/yellow stripe) wire is a safety device in case anything goes wrong with the wiring in the iron to cause a short circuit. It delivers the power along the earth wire into the ground instead of it going through the user.The Iron would work without the earth wire being connected but the user would be at risk of electric shock if the iron developed a fault or the wires came loose.
Is polyvinyl chloride an insulator of electricity?
yes, its an insulator. its a type of insulator used for wires, cables, etc
What lines delivers electricity to you home?
A power company thyough their mains wires.
Why are there 3 pins to the plug?
Because the mains supply has three wires. The Live wire (brown) is the power from the mains. The Neutral (blue) is the return to the mains (completing the circuit). The Earth (green/yellow stripe) - is the 'safety trip'.
How many wires are there inside electricity cables?
There are three! (i think)
How many wires supply electricity to your home?
There are three wires supplying power to your home two line wires @ 110 volts each and one nutral.
What is importants of electricity?
The wires and that you have the wires
When electricity flows wires into our home?
Electricity does not flow wires into your home, wires direct the flow of current into your home.
Is electricity from a home stereo to the speakers dangerous?
Usually it is about the same voltage as a few batteries, and in DC (direct current). It's not dangerous, but you could still get some pain from touching the exposes wires to anything moist on your body. However, if the speakers are "wired" or "amplified" - that is, they have their own connection to the household mains electricity, then any wire within them or sticking out of them must be assumed to have domestic voltage running through it. This is 110V/60Hz or 220V/50Hz, depending on your country. and is often fatal when played with. As with all wires in any setting, assume wires are live at mains voltage until you have proof they are not. Don't take a chance with electricity - it shoots to kill. no electricity passing from the stereo to the speakers isn't dangerous because the votage isn't high enough to do any serious damage. +++ The signal to the loudspeakers are a.c. not d.c. - almost by definition, but it is at a very low voltage though in a domestic stereo. The output from a high-power public-address amplifier can be high enough to be dangerous, although it is not from the mains. . Mains voltage throughout Europe is now 230V a.c., at 50Hz.
How was electricity captured inside of electrical wires?
Electricity is not "captured" inside of electrical wires. The question makes no sense.
Find out what wires do?
Wires just connect electricity cords/outlets.
How electricity gets to the house?
By wires.
What is a form of energy that moves through wires?
Electricity moves through wires.
How do wires work?
they carry a flow of electricity
