Why are copper and aluminum wire used as connecting wires?
Copper and aluminium are good conductors of electricity. They have very low resistance and allow the current to flow through them easily. Hence, they are used to make wires for electrical transmissions.
Why is copper wire used as connecting wire?
Copper is an excellent conductor of electricity, allowing electricity to flow freely through it. As a result, it’s employed to form wire connections. Copper has an extremely low electrical resistance when used as a connecting wire.
Why are copper and Aluminium wires used as connecting wires II Why is tungsten used for filament of electric lamps III Why is lead tin alloy used for fuse wires?
Copper and Aluminium metal are used for making connecting wires . Copper and Aluminium has high melting point and can be drawn into wires that is it is ductile. ♠ Tungsten is used as filament in bulbs and lamps because it has a high melting point of 3380° C which won’t melt easily.
Why are copper and Aluminium wires used as connecting wires II Why is tungsten used for filament of electric lamps?
(i) Copper and aluminum wires are used as connecting wires because they have low resistivity and are good conductors of electricity. (ii) Tungsten has a high melting point and great tensile strength so it used as light bulb filament in electric lamps.
Why are metals used in connecting wires?
Copper, aluminum and other metals are good conductors of electricity, so they are used for making connecting wires.
Why aluminium is used to make electrical wires?
Aluminum provides a better conductivity to weight ratio than copper, and therefore is also used for wiring power grids, including overhead power transmission lines and local power distribution lines, as well as for power wiring of some airplanes.
Why do we use metal wires to connect different elements of an electrical circuit?
We use metal wires as they are a very good conductor of electricity so they are the best source for connecting elements. Suppose we use a non-conductor then that will provide the hindrance to the flow of electron viz current.
Why connecting wires should be metals?
Textbook solution A conducting wire should have low resistance , so that electrical energy is not wasted as heat. Copper being a metal has certain physical properties which make it suitable for making connecting wires: Copper is a metal which is considered as a good conductor of electricity.
