The normal current carrying capacity is 6 amps per square millimeter without any cooling with forced cooling the number can be as high as 30 amps per square millimeter and for a motor application this means 5 times the energy density so a typical 1 or 2 KW/Kg energy density is now 5 to 10 KW/Kg in a continuous operation and peak values can be 10 times for a min or 20 times for a few seconds. The limiting factor is the thermal effects and how you deal with them the more efficient the heat removal the higher the allowed level of current.
Current US quarters are made of a "sandwich" consisting of a pure copper core clad on both sides with a layer of cupronickel alloy (25% nickel and 75% copper). Overall, copper makes up about 92% of the coin by weight. Current Canadian quarters are made of an alloy of 94% steel and 3% copper, plated with nickel.
The current clad version is two layers of copper/nickel (75% Copper, 25% Nickel) on a core of pure copper giving a total composition of 8.33% Ni with the remainder Cu.
Current Canadian dimes are made of steel. Before that they were made of nickel, and up till 1967/68 they were made of various alloys of silver and copper. Current US dimes are made of a metal "sandwich" consisting of outer layers of 75% nickel and 25% copper bonded to a core of pure copper. Up till 1964 US dimes were made of 90% silver and 10% copper.
The resistivity of copper at 75 degrees Celsius is approximately 1.68 x 10^-8 ohm-meters. Resistivity is a material property that quantifies how strongly a given material opposes the flow of electric current. In the case of copper, its low resistivity makes it an excellent conductor of electricity, which is why it is commonly used in electrical wiring and other applications where high conductivity is desired.
What is current carrying capacity of 50x8 mm copper flatbusbar.
it is an infinite current carrying conductor which doesn't have voltage drop.
12 swg current carrying capacity
170A
570amps on 3phase 415volts
30 amps
in air it will be 665Amps.
It can carry upto 100 Ampere.
25 amps, 6000 watts
1 sq..mm have max. capacity is 10 ampere if these are of copper approximately than 120 sq..mm having current carrying capacity is 1200 ampere
The larger in diameter the wire is, the larger the current carrying capacity the wire has.
I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
