Watts (Watts); It's a unit of power! 1 watt is one joule per second. In electricity, it's the product of voltage and current! 1 kilowatt is 1,000 watts, which is equivalent to horsepower. It is not a unit of virtue, but a unit of merit.
Current; It's a physical quantity! Refers to the magnitude of the current flowing through the conductor. In purely resistive debt-borne circuits; Current = voltage divided by resistance.
Current conversion is not a simple matter, and the current calculation of AC load circuits requires AC inductive impedance in addition to calculating the circuit impedance. Capacitive liabilities are also calculated for capacitive reactance.
Ohm's law only expresses the relationship between voltage, resistance, and current, and it is not so simple in the analysis of energy circuits, first of all, you have to regard voltage as electromotive force!

Generally, all three items are calculated according to kilowatts and two amps: 380V = 2A
And (220v = Note: The efficiency and power factor of the load will also be different).

The two units cannot be compared, just like the question of how long is an hour, 1 kilowatt may have nothing to do with electricity at all, such as my car is a liter cylinder, 75kw of power. It has nothing to do with electricity, kw is the power that does not necessarily have to be the ability of electricity to do work, such as the power that a person can usually emit continuously. There is also a unit of work called how much horsepower, which is also a unit of power, and horsepower and kw can be converted to each other.

Kilowatts and currents cannot be converted. Kilowatt is the unit of electrical power and the unit of electric current is amperes.

The unit of watt is the unit of power, and the two are not comparable and cannot be converted. Watts (W) = Amps (a) volts.
v) Without voltage, current and power cannot be converted. p (power) = u (voltage) * i (current), the unit of power is watts (w), the unit of voltage is volts (v) and the unit of current is ampere (a).

1 kilowatt current is ampere. When the voltage is 220 volts, 1 kilowatt has ampere, 380 volts is ampere, and more than this voltage belongs to high voltage, 6000 volts are ampere, and 10000 volts are ampere. Power and current should be converted according to the voltage value, current (amps) voltage (volts) power (watts).
Direction. Physically, the direction of the current is specified, which is the direction of the positive charge's directional motion (i.e., the positive direction of the speed of the positive charge's directional motion or the opposite of the speed of the negative charge's directional motion). The direction of current motion is opposite to the direction of electron motion.
Charge refers to the free charge, which is free electrons in metal conductors and positive and negative ions in aqueous solutions of acids, bases, and salts.
Current flows from the positive electrode to the negative electrode outside the power supply, and from the negative electrode back to the positive electrode inside the power supply.

Power divided by voltage equals current. There are several currents in a kilowatt, depending on the voltage used. One thousand volts of voltage, one kilowatt of power (1000 1000 = 1) and the current is one ampere.
308 volts 1,000 watts of power (current 2.63 ampere. Twelve volts of power (1000 12 = current is eighty-three .33 amperes.

For 10000V voltage three-phase system, 1kW is the current; Kilowatt is a unit of electric power, and the unit of current is ampere, and there is no direct relationship between the two. Electrical power refers to the work done by an electric current per unit of time.
It is denoted by the symbol p. p=w t=i* is the electrical energy, t is the time, i is the current, and u is the voltage, so the electrical power is also the product of the current flowing through the electrical device and the voltage applied to it. Its measurement can be measured with a special power meter connected to the ** road.

According to the experience of the industry, one kilowatt of a general electric motor is equal to two streams. That is, 1000 watts corresponds to two amperes, of course, this is an empirical value, if you look at it according to the name brand, then it is definitely a little smaller than two currents.

Kilowatt is a unit of power, which is the product of the working voltage and working current of an electrical appliance. For example, 100V.
How much current is one kW at?

Power is equal to voltage * current, so to know what the current is, it depends on what the voltage is.

1 kilowatt of electrical equipment does not count the power factor in the case of 220V when the current is about 220V, that is, the amount of current per moment is, weAssumptionsis per second, then 1 hour is 3600 seconds, which is 16363a. But this algorithm is hypothetical and does not hold.

It depends on how many volts the rated voltage of the appliance is used. If it is 220V voltage, the current should be 1000 220;
If it is a 380V voltage, the current should be.

There is a "problem" with this question, just like asking: how many rice is a catty. Or how many meters is 1 cubic meter.
1 kWh = , broken down is: thousand. Submit.
Quiet. (the power factor is considered as 1). That is, a user of 1kw works for 1 hour.
Current is the number of charges passing (flowing) per unit of time, 1a, which is the number of charges flowing through 1 coulomb per second. Therefore, it is not possible to get (or derive) the correct current from kWh.

The unit of voltage is volts (V) and the unit of current is ampere (A).

A wire is a wire that transmits electrical energy. It is divided into bare wire, magnet wire and insulated wire. Bare wires have no insulating layer, including copper, aluminum flat wires, overhead stranded wires, and various profiles (such as profile wires, busbars, copper bars, aluminum bars, etc.). It is mainly used for outdoor overhead and indoor busbars and switch boxes. >>>More
