What is the kilowatt hour per kilowatt hour?

What is the kilowatt hour per kilowatt hour?

They are units of work that cannot be converted to each other
If we multiply the power by another time, then the result is work. The unit of work is Joule and kilowatt hour. Kilowatt hour is usually called "degree". The relationship between them is as follows:
1 J = 1 W · s
1 kwh = 1 kW · H = 1000 W · H = 1000 * 3600 w · s = 3600000 joules
Namely:
1J=1W·s
1kWh=1kW·h=1000w·h=1000*3600w·s=3600000J
How many milliamps equals one degree of electricity
How long does my device last
An hour's energy consumption of an electrical appliance with one degree of electricity equal to 1000 W
The power of electrical appliances is 220 V * 55 Ma = 220 V * 0.055 a = 12.1 W
1000 / 12.1 = 82.6 hours per kilowatt hour
However, considering other consumption, this is only an ideal value. It would be nice to have about 70%
How many MAH is one kilowatt hour? Urgent!
A kilowatt hour is a kilowatt hour, and a thousand milliampere hours equals one watt, so a kilowatt hour equals 1 * 10 ^ 6 milliampere hours
[beautiful mood] team, sincerely solve your doubts, please accept!
25 square aluminum core cable, about 100A current 25 square copper core cable, about 140A current 25 square aluminum core cable, using 220 v
Can you tell me the specific formula
The principle of cable selection is [simple algorithm]:
The current carrying capacity of the conductor with cross-sectional area less than 10mm2 (including 10mm2) multiplied by 5 is the current carrying capacity of the conductor with cross-sectional area
The corresponding cross-sectional area is more than 100mm2 multiplied by 2
16mm2, 25mm2 times 4
35mm2, 50mm2 times 3
70mm ~ 2, 95mm ~ 2.5
If the conductor passes through the pipe multiplied by a factor of 0.8 (the total cross-sectional area of the conductor passing through the pipe does not exceed 40% of the cross-sectional area of the pipe)
Use in high temperature places multiplied by coefficient 0.9 (within 85 ℃)
The cross-sectional area of bare wire (such as overhead bare wire) multiplied by the corresponding ratio and then multiplied by 2 (such as 16mm2 wire: 16 * 4 * 2)
The above is calculated according to the sectional area of aluminum wire
The current carrying capacity of 1.5mm2 copper wire is equal to that of 2.5mm2 aluminum wire, and so on
How many joules is one electron volt?
RT
Electron volt (EV) is the unit of energy. It represents the kinetic energy of an electron (with a charge of - 1.6 × 10-19 Coulomb) accelerated by an electric field of 1 volt. The conversion relationship between electron volt and energy unit Joule (J) in SI system is 1 eV = 1.60217653 (14) × 10-19 J (sou
Power / 380V * 1.73 = current formula
The current of a single wire should be calculated
What's the problem?
Two resistors are in parallel, one is equal to 4 Ω, the other is equal to 6 Ω. How much is the total resistance?
The formula for parallel connection of two resistors is: r = r1r2 / R1 + R2. In your case, r = 4 * 6 / (4 + 6) = 2.4, and the total resistance is 2.4 Ω
How much current can 4 square copper wire bear?
How to calculate
If the cross-sectional area of the conductor is not more than 50 mm 2 multiplied by 30.5 mm 2 (including the cross-sectional area of the conductor) and the cross-sectional area of the conductor is not more than 50 mm 2 multiplied by 30.5 mm 2 (including the cross-sectional area of the conductor tube), the simple algorithm is to multiply the cross-sectional area of the conductor tube by 20% ）The cross-sectional area of bare wire (such as overhead bare wire) multiplied by a factor of 0.9 (within 85 ℃) and then multiplied by 2 (such as 16mm2 Conductor: 16 * 4 * 2) is calculated according to the cross-sectional area of aluminum wire. Copper wire upgrade calculation means that the current carrying capacity of 1.5mm2 copper wire is equal to that of 2.5mm2 aluminum wire, and so on, If other factors are taken into account, please compare the calculation
How many joules does an electronic Ford equal?
Electron volt is the unit of energy, abbreviated as ev. It represents the kinetic energy of an electron (charged e = - 1.6 * 10 ^ (- 19) C) accelerated by an electric field of one volt. 1eV = 1E x 1V ≈ 1.602x10 ^ (- 19) C · v = 1.602x10 ^ (- 19) J
The - 19 power J of 1eV = 1.6 * 10
How much current and watts can 1.5, 2.5, 4, 6 and 10 square millimeter wires bear? It is better to have calculation formula,
The approximate calculation is as follows: 1.5-10mm2 conductor cross-sectional area multiplied by 5 times
