How many catties of 16 square single strand copper core wire per meter How many jin copper per meter of 16 square single strand copper core wire?

1*16*10^（-6）*8.9*10^（3）
=0.1424kg
It's 0.28 Jin, less than three Liang
What is the diameter of 95 square single strand copper wire or 70 square diameter
The 95m2 wire usually adopts 21 strands or 27 strands to form a wire, and the diameter of each thin wire is different with the number of strands; if the diameter of a complete 95m2 wire is d = 1.13 * square of wire number = 1.13 * 95 = 11mm
What to do when 380V is changed into 220V?
At home, the main switch of 220 V power leakage always trips. Just push it up, and the sub switch never jumps. It is used to change 380 V into 220 V in the house. By the way, the home is powered by 380 power supply in the air conditioner room in the yard, and then connected to 2 220 V power supply for electrical lighting in the house. The 380 V power supply never jumps, that is, the 220 V main leakage switch in the house jumps
My capacity is large enough. The total power of my home is no more than 1000 watts when the power is cut off, and my maximum capacity is 15 kW. It seems that there is no leakage. If there is leakage, it should not be pushed up at that time
That's right. 380V is three wires. If you get two wires, you will have problems. You should get all three wires into the house and distribute them equally. If you only use two wires, it will lead to the imbalance between the three phases, so it will trip. The specific method is to distribute the three wires equally to all indoor consumers
How to calculate the sectional area of copper wire with diameter of 1.33
The formula cross-sectional area = Πr & #178; Πis the circumference, R is the radius = 1.33 △ 2 = 0.665,
So the cross-sectional area is 3.14 × 0.665 and 178;
= 1.3885865 (square ··)
The resistance of a section of conductor with uniform thickness is 1 ohm. If its length is extended to 100 times of the original, how much ohm will its resistance be?
Come on, I want to,
unchanged
10000 times
The area becomes 1 / 100 and the resistance increases 100 times
At the same time, the length becomes 100 times, and the resistance increases 100 times, so 100 * 100 = 10000 times
unchanged
How many watt seconds is a kilowatt hour? How many joules?
Watt second is Joule, and one kilowatt hour is 3.6 * 10 ^ 6 Joule,
I hope it will help you
How to connect the 220 V heating tube with 380 V electricity?
Each heating tube has two feet. One of the feet of each heating tube is connected together as the midpoint of the star connection method. The other foot of each heating tube is connected with phase a, B and C lines respectively. If there is a zero line, the midpoint is connected with the zero line. If there is no zero line, it will not be connected
Formula s for calculating cross sectional area of copper wire by power line pressure drop=
The conductor length resistance can be calculated only when there is load current to produce voltage drop or allowable voltage drop
R＝U/I
(U = voltage drop, I = load current)
The formula for calculating the sectional area of copper wire is as follows:
S＝ρ×L/R
(copper wire resistivity: ρ = 0.0172, l = wire length)
In addition to the external temperature, there are also ---, ---, and ---?
Material, length, cross sectional area
How many joules is 0.005 kwh
0.005KW=5W
1H=3600S
P=3600S*5W=18000J
0.005Kwh=0.005*(3.6*10^6)J=18000J
