How many watts is a kilowatt hour

How many watts is a kilowatt hour

It is not the same concept that the two are not equal
The relationship between the magnetic induction intensity of the magnetic field around the conducting wire and the distance from the conducting wire
Is the closer to the conducting wire, the greater the magnetic induction?
If the wire is long and straight, the relationship between the current I in the wire and the magnetic induction B far away from the wire R is linear
B = k * I / R, K is constant
The closer to the wire, the greater the magnetic induction (when the current in the wire is constant)
What's the absolute negative value of a
If a is negative 2, what is the absolute value of negative 2?
-A (negative a)
How many degrees is a kilowatt hour?
Once, this is the concept of degree
Two long straight wires are parallel to each other, and the current of equal size and opposite direction is applied to the two wires in the space with equal distance
A is equal to zero
B is not equal to zero and the direction is parallel to the wire
C is not equal to zero and the direction is perpendicular to the two conductors
D is not equal to zero, and the direction is from one wire to another
A constant direct current will produce a stable magnetic field around it. That's right. Another example experiment in physics textbook is that a compass is placed vertically below a horizontal wire, parallel to the wire. When the wire is electrified with direct current, the compass turns to be perpendicular to the wire
For example: 6 + | - 6 | =? (= 12 right?) 6 + | - 6 | =? (= 12 right?)
But a friend of mine told me that 6 + | - 6 | = 0. Does anyone have any hair?
That's right!
Just remember that the absolute value of both positive and negative numbers is positive, and the absolute value of 0 is 0
The absolute value of a negative number is its opposite
Or it's simpler - the absolute value of a negative number is to remove the negative sign, and the absolute value of a positive number is itself
After the absolute value sign is removed, it can be calculated according to the primary school's addition and subtraction method!
Take your example: 6 + | - 6 | = 6 + (- (- 6)) = 6 + 6 = 12
Come on^_^
Right ~ ~ 6 + | - 6 | = 6 + 6 = 12
6+|6|=6+6=12
|-6|=6，|6|=6
Your above formula is correct
The absolute value of a positive number is a positive number, and the absolute value of a negative number is also a positive number
Just remember that
You just need to add and subtract the numbers without looking at the symbols
How many kilowatts of electricity is one watt? I don't want to say that one kilowatt hour is one kilowatt hour. I also know that to be specific
Watt is the unit of power, kilowatt hour and kilowatt hour are the unit of electric energy. These two cannot be confused. There is a theoretical error in this question, and there is no answer. It's like asking how many seconds a meter is equal to
F = L in bil is the length of the wire. Is that the length of the wire in the magnetic field or the whole length of the wire?
For example, if a wire is 20m long and the part in the magnetic field is 10m, which value should I substitute into l?
Neither, but the effective length of cutting
For example, if your whole wire is in a magnetic field, but it moves parallel to the magnetic field, it will not be subject to ampere force
If you mean "the part in the magnetic field is 10m, and the direction of motion is perpendicular to the magnetic field", of course, it is substituting 10m
Because the absolute value of a negative number is equal to its opposite number, if | x | = - x, then X
No, it should be X
Wrong
It should be x ≤ 0
Incorrect, such as x = 0
Wrong, because x can also be equal to 0
| x | ：
If x is a positive number, then | x | = X
If x is negative, then | x | = - X
If x is 0, then | x | = 0
What milliampere is equal to one kilowatt hour of electricity
Theoretically, it takes only two to three seconds for a 1.2-volt ordinary No. 5 battery to charge, and it takes only about 20 seconds for a 12 volt (1800mAh) battery. But the battery has internal resistance. The internal resistance of No. 5 battery is about 100-500 milliohm, and that of a 12 volt lead-acid battery is about 1-2 ohm
