What is the formula to calculate load voltage?
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
What is the formula of ampere?
The formula for amperage is:I = V / RI = amperage, V = voltage, and R = resistance.Also amperage can be found by using the following formulas.I = P / V, Amps = Watts/VoltsI = sq root P/R, Amps = the square root of (power divided by resistance) watts/ohms.
Unit of electric power determined by muliplying volts times amperes?
Power=Volts x Amps Unit for power is watts
A 2.5 Amperes current flows through a 100W lamp what is the voltage?
The formula you are looking for is E = W/I.
What is the formula to convert amperes from 440V to 460V?
For the same power - Watts - you need to run twice as many amps at 220V than at 440V. For the same load, it'll pull half the amps at 220V than it did on 440V

How much is 480 ka is that 480000 amps?
Work it out yourself, apparent power = supply voltage x load current. This, of course, will give you the apparent power in volt amperes, not kilovolt amperes -so you will need to divide your answer by 1000 if you really do need your answer in kilovolt amperes! And the symbol for kilovolt amperes is 'kV.A', not 'kva'.
Is a kVa the same as an amperes?
KVa is not the same as the amperes because KVa is the unit for reactive power while amperes is the unit for current.
What is the definition of active power?
'Active power' (also known as 'true power' and 'real power') is the rate of energy dissipation by the in-phase component of current in an AC circuit, expressed in watts.Active power is the vector-difference between apparent power (measured in volt amperes) and reactive power (measured in reactive volt amperes).Expressed in terms of apparent power: Active Power = Apparent Power x power factor = U I cos (phi)
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
What does the letters MVA represent in electrical terms?
Mega volt amperes

Formula for 7.5va convert into Amperes load comsumption?
Volt Amps conversion
Unit of electric power determined by muliplying volts times amperes?
Power=Volts x Amps Unit for power is watts
True power divided by apparent power?
Real Power: The actual power in Watts or K-Watts in AC or DC Circuits Apparent power: The Power in Inductive or Capacitive Circuits have Phase Lag & Lead measured in Volt Amperes VA or Kilo Volt Amperes KVA
Do amperes have more power than watts?
You can't really compare that. Amperes and watts measure completely different things. On the other hand, any time there are amperes, there are also watts. The relationship is:P = I^2 x R or in units: watts = amperes squared x resistance
What is an eletric current measured in?
If you refer to the units, power (any power, not just electrical power) is energy divided by time. The SI unit is the watt, equal to 1 joule/second.
