What is the current voltage wattage conversion, kilowatt conversion current formula

Power, voltage, current.

Current I, Voltage V, Resistance R, Power W, Frequency F

w=i squared multiplied by r

v=irw=v squared divided by r

Current = Voltage Resistance.

Power = Voltage * Current * Time.

Current I, Voltage V, Resistance R, Power W, Frequency F

w=i squared multiplied by r

v = IR current i, voltage v, resistance r, power w, frequency fw = i squared times r

v=irw=v squared divided by r

The relationship between voltage v (volts), resistance r (ohms), current intensity i (amps), and power n (watts) is:

v=ir，n=iv

i*i*r, or it can also be deformed as: i=v r, i=as AC.

Current = i, voltage = u, resistance = r, power = p

u=ir,i=u/r,r=u/i,p=ui,i=p/u,u=p/i

Voltage U = Power w Current I

Current i = power w voltage u

Power w = voltage u current i

The above three parameters are independent of time, only when it comes to the amount of work done by the power supply, the time parameter is introduced, and the power w time t is equal to the amount of work done by the power supply, and its unit is joules.

1 kilowatt isElectrical power, can not be closed mold directly converted into current.

Voltage (v) Current (a) Power factor.

cos ) = power (kw), input the voltage and power factor into the noisy trillion formula, set the power to 1, and calculate it.

KWh. It is the so-called "degree" of rent increase, which is the unit of electric work, symbol: kw·h, and the calculation formula is power multiplied by time. Suppose the power of a power-hungry device is 2500 watts, that is, its power consumption in one hour is kilowatt-hours, which is one hour of electricity.

The relevance is as follows. The unit of work is joules.

and kWh, the relationship between them is as follows:

1 joule = 1 watt second.

1 kWh = 1 kW 1 hour = 1000 watts 1 hour = 1000 watts 3600 seconds = 3600000 joules.

i.e.: 1 kWh = joule.

For everyday life, 1 kWh is 1 degree.

The known power is kilowatts (p), and the voltage and power factor must be known to calculate the current.

Wait. The calculation formula: current i = p 3 u cos, where p power single pin dispersion.

kw, u voltage unit kv, calculated current i unit a.

In the case of a single-phase circuit, the current i=p u cos is calculated.

Summary. Hello! We're happy to answer for you!

Current is a physical quantity that represents the magnitude of the current, and kilowatt is a physical quantity that indicates the magnitude of the electric power, and the two cannot be converted. However, the relevant formula is p=ui=i 2*r

How are currents and kilowatts converted.

Hello! We're happy to answer for you! Current is a physical quantity that indicates the magnitude of the current and kilowatt is a physical quantity that indicates the magnitude of the electric power, and the two are incompatible. However, the relevant formula is p=ui=i 2*r

Hello! It is known that the current is 4800A, how to calculate it!

Good. What is the voltage?

If it is 380, that is: 4800*380=1824000w that is, 1824kw

The method of calculating the power (watts) required for the current depends on other parameters that you already know. In general, the following formula is used for calculation:

Power (watts) = current (amps) and voltage (volts).

If you know the current (amps) and voltage (volts), you can calculate the power by multiplying them directly by the hood. For example, if the current is 5 amps and the voltage is 220 volts, the power is:

Power = 5 amps 220 volts = 1,100 watts.

If you only know power and voltage, you can calculate the current using the following formula:

Current (amps) = power (watts) Voltage (volts).

For example, if the power is 1500 watts and the voltage is 110 volts, then the current is:

Current = 1500 watts 110 volts amps.

Note that these formulas apply to DC circuits and in the case of constant voltage or current. For AC circuits, the calculation may be slightly different due to the phase difference involving current and voltage (since the frequency of AC is 50 or 60 Hz). In addition, in practical applications, it is also necessary to consider the influence of resistance, inductance, capacitance and other factors on the slippery flow and power.

Therefore, the specific method of calculating the power required for the aplex current depends on the parameters you know and needs to be appropriate for the type of circuit you are dealing with. In practice, to ensure accuracy and safety, it is best to rely on instruments and equipment for the measurement and calculation of current, voltage, and power. <>

Voltage x Current = Power, Voltage Resistance = Current, Current x Resistance = Voltage.

In the same circuit, the current through a conductor is directly proportional to the voltage at both ends of the conductor and inversely proportional to the resistance of the conductor, which is Ohm's law.
