What is 148 degrees minus 75 degrees?
148 degrees minus 75 degrees is 73 degrees
What is 75 Celsius to Fahrenheit?
75 degrees Celsius = 167 degrees Fahrenheit.
How many degrees are there in three fourths of a circle?
3/4 equals 75%. 75% of 180 degrees is 135. .75 x 180 = 135 degrees.
What is 75 Fahrenheit converted to Celsius?
75 degrees Fahrenheit is 23.9 degrees Celsius.
How many degrees Celsius is 167 degrees Fahrenheit?
75 degrees celcius.
Why is copper used for electricial wiring?
Because copper has a very low electrical resistivity of 16.78 nΩ·m, meaning it's easier for electricity to pass through it. For comparison, nickel has a resistivity of 69.3 nΩ·m and iron's resistivity is 96.1 nΩ·m.
How do you calculate resistivity of copper wire?
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!
Why is copper wire the best known conductor?
The best electrical conductor known is silver, not copper. Electrical resistivity of silver: 1,59.10-8 ohm.m Electrical resistivity of copper: 1,68.10-8 ohm.m A good electrical conductor has a very low electrical resistivity and a high electrical conductivity (the same principles for the thermal conductivity).
Can you use copper wire instead of eureka wire in finding its resistivity?
no
What is the resistivity of copper at 77 K?
0.213 n ohm - m
Which one of the following has the lowet resistivity -aluminium -copper -steel -lead?
Copper, aluminum, steel and lead in that order.
Is lead a good conductor of electricity in all the states?
The resistivity of lead is 208 n.Ohm.m (at 20 degrees celsius) in comparison, the best conducter, silver, has a resistivity of 15,87 n.Ohm.m widely used conducter, copper, has a resistivity of 16,78 n.Ohm.m , considered to be a good conductor resistivity of iron, considered not to be the a good conductor at all is 97 n.Ohm.m So no, lead is not a good conducter. But keep in mind, it's still a conductor, don't use it as an isolation!
What is the specific resistance of copper and aluminum?
Copper is widely use in the US, it has the second lowest resistivity, behind silver, which is much more expensive making copper the best choice. It resistivity at 20 °C is 1.72×10−8
What wire should you use for 50 amp?
A #6 copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
What gauge stranded copper wire for 100 amp service?
A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 115 amps respectively. A #1 aluminum conductor with an insulation factor of 75 or 90 degrees c is rated at !00 and 115 amps respectively.
What size aluminum wire would replace a four gage copper wire?
A #4 copper wire with an insulation factor of 75 or 90 degrees C is rated at 85 amps. A #2 aluminum wire with an insulation factor of 75 and 90 degrees C are rated at 90 and 95 amps respectively.
Why copper strips are used in meter bridge wire?
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.
