What is the aluminum wire equivalent to?
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
What element is found in aircrafts automobiles welding and cooking utensils and is used for transmit electricity?
aluminum
Which metal is used for electrical contacts?
Copper is used the majority of the time. Gold is sometimes because it does not corrode. Tungsten is used in light bulbs because it is a good resistor and resists the flow of electrons. Aluminum and silver are also sometimes used. There is also some recent research in safely using sodium and lithium.
What size wire for a 200 amp commercial service?
2/0 in Copper and 4/0 in Aluminum. This is referred to as two ought and 4 ought. <<>> A #2/0 copper conductor with an insulation factor of 90 degrees C is rated at 185 amps. In Canada, a # 2/0 wire is allowed to be used for residential 200 amp services only instead of using #3/0. This rule helps the home owner to keep building costs lower. A #3/0 copper conductor with an insulation factor of 90 degrees is rated at 210 amps
Why is aluminum or copper wire not used as fuse wire?
Because those metals have a high meling point, so it's easier and safer to use fuse wire which melts at a lower teamp.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
Kushite farmers used iron in their hoes and what instead of copper or stone?
Aluminum
How do copper cables work?
They conduct electric signals. Copper is a fairly good conductor, that's why it is often used instead of other metals.
Why copper and aluminum are used in electrical cables?
Because they have low electrical resistance, good enough mechanical properties and aren't too expensive.
Why would a Chevy Corvette be hard to start?
A lot of the time Chevy used aluminum battery cables in their cars,(in particular my 1980) I was continually having starting and battery problems until I replaced the cables with copper.
What is the element that is used for eletrical cables?
copper
What two metals are commonly used in their purest form?
Copper (electrical wiring and hot water pipes) and aluminum (high voltage cables and soda drink cans).
What metals are used for earrings?
Aluminum and copper
Which is the best conductor among these gold silver copper or aluminum?
Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.
How has copper been used?
Copper has been used lately in wires and cables like coaxial and electric wires.
Can you change from aluminum wire to copper wire in a new oven?
Copper is preferable to aluminum and the size of wire should be the same or the next size down if copper is used.
Why does security alarm systems use cables with one conductor Aluminum and one Copper?
Both conductors are copper. One is just electroplated so it looks silver. This is so you can know which conductor is which when you hook them up. The copper-colored conductor is traditionally used as the positive, or plus wire. The silver-colored wire is used for the negative or minus wire. Some cables use a foil shield. The shield is mylar (polyester) coated with aluminum. The shield is not really one of the conductors, it is only used to drain away interfering signals before they reach the inner conductors, so it need not be a super good conductor. Aluminum is used for the foil shield partly because it is lightweight, but mostly because it's much cheaper than copper.
