We don't generally use silver electrical wires because silver costs more than copper and is only marginally better as a conductor. Economics and practicality dictate our choices here. Copper is a much more common metal than silver.
Copper is an excellent conductor of electricity. Among metals it is second only o silver, which is too expensive for practical use in wiring. Copper is also extremely ductile, meaning it can be easily drawn into wires without breaking.
I believe you've managed to turn wires inside out. (conducting) wires are covered in insulating plastic. And it is done this way to prevent electrical energy from going where it is not wanted, such as into you.
Even though silver is the best conductor of electricity, it is extremely expensive. Thus silver is not used to make electical wires. Silver is also very soft to be used as electric wires.
For electrical conductivity silver has not much advantage copper is much cheaper. The electrical conductivity advantage for silver is in the ratio 63.0 to 59.6. Silver 18.50 USD/oz Copper 3.8 USD/lb Note the different units for the comparison.
because it can can cause fire or electrical shock.
Silver is not used for electrical wires mainly for two reasons. Silver is too expensive to use and it is a soft metal which is not suitable for electrical wires.
To strip electrical wires and to twist mutliple wires together.
Silver is not commonly used in electrical wires due to its high cost compared to other metals like copper and aluminum. While silver has a higher conductivity than copper, the difference is not significant enough to justify the increased cost. Additionally, silver is softer and more prone to corrosion, making it less practical for use in electrical wiring.
wires that have got good conductivity and less losses
Silver is one of the best electrical conductors. It is used in a lot of electrical contacts.
Acids such as sulfuric acid or aqua regia can corrode and destroy electrical wires. It is not recommended to use chemicals to intentionally damage electrical wires, as it can pose safety hazards and is illegal.
copper next good conductor to silver . it is cheaper .malleable ductile mechanically strong abundantly available so we use
Copper is the best material for electrical wires due to its high electrical conductivity and low resistance, which allows for efficient transmission of electricity. Silver is slightly more conductive than copper but is much more expensive, while gold, while highly conductive, is even more expensive and less practical for everyday use.
No.
some simple machines do need wires and some dont
To cover exposed electrical wires safely and effectively, you can use electrical tape or wire nuts to insulate and secure the wires. Make sure to turn off the power before handling the wires and consult a professional if you are unsure about how to properly cover them.
To locate electrical wires in walls, you can use a stud finder with a built-in electrical wire detection feature. This tool can help you identify the presence of wires behind the walls before drilling or cutting. Additionally, you can use a non-contact voltage tester to detect live wires without direct contact. It is important to exercise caution and follow safety guidelines when working with electrical wiring.
