It is often said that how to calculate 1kW two ampere current
1kW two ampere current calculation (approximately): I = 1 / (1.732 * 0.38 * 0.78) = 1.95a
Add, subtract, multiply and divide four numbers (each number must be used and can only be used once) to make it equal to 24
Using the above rule, we get = 24
(1) 6 divided by 3 times 10 plus 4
(2) Three times six plus ten minus four
(3) 3 times 10 minus (6 minus 4)
I will come up with three, I hope the landlord is satisfied
If there are other ways, please post
3×【10-（6-4）】=3×8=24
3x（10-6+4）=24
[+4]x3=24
3x6+10-4=24
[10 - (6-4)] X3 or 6 / 3x10 + 4 or 3x6 + (10-4)
=（10-2）x3 =2x10+4 =18+6
=8x3 =20+4 =24
=24 =24
I hope my answer can help you
Second grade physics unit conversion questions (length, area, volume, mass, density, speed), with answers
For example: the density of iron is 7.8 × 10 ^ 3kg / m ^ 3; = () g / cm ^ 3;. This problem can be solved by using the basic method in unit conversion, that is, how many times the unit in the molecule becomes smaller, how many times the converted value becomes larger: 1kg = 10 ^ 3G; how many times the unit in the denominator becomes smaller, how many times the converted value becomes smaller: 1m ^ 3; = 10 ^ 6cm ^ 3;, therefore, 7.8 × 10 ^ 3kg / m ^ 3; =7.8 × 10 ^ 3 × (10 ^ 3 / 10 ^ 6) g / cm ^ 3; = 7.8 g / cm ^ 3;; according to this conversion method, we can get a rule of density unit, that is, for the density of a substance, when we use "g / cm ^ 3", "kg / DM ^ 3;" and "t / m ^ 3;" as units, their values are the same; =8 T / m ^ 3;. This "7.8" is obtained by deleting 10 ^ 3 from the density value of iron in the density table in the textbook. Remembering this rule not only brings great convenience to the conversion of density units, but also makes some problems related to density calculation simple. For example, using this method to calculate the mass of water is 1cm ^ 3; (ML) the mass of water is 1g, 1dm ^ 3; the mass of water is 1g, 1dm ^ 3; The mass of water is 1 kg, 1 m ^ 3; the mass of water is 1 ton
Examples
Using images to express physical concepts and laws is a common problem in junior high school. Understanding the physical meaning of images is helpful for us to analyze the problems and deepen our understanding and application of physical concepts and laws. Example 1 Figure 1 shows the relationship between the mass and volume of a, B and C, which can be seen from the figure ()
A. ρ a > ρ b > ρ C, and ρ a > ρ water
B. ρ a > ρ b > ρ C, and ρ a > ρ water
C. ρ C > ρ b > ρ a, and ρ a, ρ b > ρ a, and ρ a > ρ water
[analysis] using the intuitiveness of the image, we can easily compare the density of the three substances. According to the definition of density, we can compare the mass (ordinate) of the three substances a, B and C with the same volume (abscissa), and the greater the mass, the greater the density; we can also compare the volume (abscissa) of the three substances a, B and C with the same mass (ordinate), When MC = MB = ma = 30g, VC ρ a
It can be seen from the image that the ratio of the ordinate (mass) to abscissa (volume) of any point on the line ob is 1g / cm, which indicates that the density of this material is the same as that of water, or this material is water (ρ B = ρ water), so it can be determined that ρ A is the same
People often say how to calculate 1kW two ampere current
0.38kv is the approximate value, using the power formula 1kW = 1.732 * 0.38 * current
Is the calculation order of the four mixed operations of addition, subtraction, multiplication and division in Volume 2 of primary school mathematics from left to right or multiplication and division before addition and subtraction?
The calculation of units at the same level (addition and subtraction, multiplication and division) is from left to right. The calculation of units at different levels is from left to right after multiplication and division

People's education press second year physics length unit conversion problem I am very anxious students
The common units of length are light year, kilometer (km), meter (m), decimeter (DM), centimeter (CM), millimeter (mm), micron (m), nanometer (nm). The international unit is m. 10km = nm, 10-4m = mm, 104mm = m, 1
How many amperes does a 3kW single-phase motor have and how to calculate the current
The rated current of 3KW single-phase motor is about 18a
Rated current = rated power / (rated voltage * power factor)
