1mva equal to how many kw?
Basically VA is the same as watt. Kilo means thousand, Mega (abbreviatted M) means a million.AnswerThe watt and the volt ampere are used to measure two different quantities and, so, cannot be directly converted one to the other. The watt is used to measure 'true power', while the volt ampere is used to measure 'apparent power'.There is, though, a relationship between the two, as the true power of a load is equal to its apparent power multiplied by the power factor of that load. So, if you know the power factor (which can vary from 0 to 1), then you can determine the true power of a load, if you are given its apparent power.Incidentally, SI doesn't recognise either the volt ampere (apparent power) or reactive volt ampere (reactive power); all forms of 'power' are measured in watts in SI. The volt ampere and the reactive volt ampere are best described as 'traditional' units.
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.
If an EMF of 1 volt causes a current of 1 ampere what is the resistance of the material through which the current is flowing?
1/1 = 1ohm MR. volta [italian] Determined that it would take 1 volt to pass 1 amp trough a 1 ohm resistor MR ampere [ french] Ditermined that it would take 1 ohm and 1 volt to pass one ampere MR ohms [english] determinaed that for 1 volt and one ampere the resistance must be 1 ohm. mr watts determined that the product of volts x ampere will equal one watt [power]
What is the current being drawn by a 100W light bulb and what is the resistance of a 100W light bulb?
Assume the rating of 100W refers to operation on a supply of 117 volts.Power = (voltage) x (current)Current = (power) / (voltage) = 100/117 = 0.855 ampere (rounded)Power = (voltage)2 / (resistance)Resistance = (voltage)2 / (power) = (117)2 / 100 = 136.89 ohms
What are Ohms Law and the Power Law?
Ohms Law is used for the measurement of resistance. You can find the resistance in a series circuit using this equation; amps=volts/resistance or volts=amps x resistance.The Power Law is used to find the wattage in the circuit. You can find the amount of watts using this equation: watts=volts x amps.CommentOhm's Law has nothing whatsoever to do with either resistance or power.The equation, R = E/I, is derived from the definition of the ohm, and not from Ohm's Law.Ohm's Law simply describes a linear relationship between the potential difference across a conductor and the current through it. It does NOT describe the relationship between potential difference, current, and resistance.
What is the difference between an ampere and an ohm?
Ampere is a measurement of electrical energy power flow Ohms is the measurement of resistance to flow of energy
What is the difference between Kilovolt Ampere and Kilowatt?
A kilowatt is an unit of true power in an AC circuit -as measured by a wattmeter. A kilovolt ampere is an unit of apparent power in an AC circuit, which is the product of the voltage across a load by the current through it. The relationship between the two is: kilowatt = (kilovolt ampere) x (power factor of load)
What is the relationship between current and power?
P=I^2*R where P=power I=Current R=Resistance
How calculate kilovolt-ampere?
25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
Power (watts) = current (amperes) * voltage (volts) Current (amperes) = voltage (volts)/resistance (ohms) 120 watts = current * 120 volts current = 1 ampere 1 ampere = 120 volts/resistance resistance = 120 ohms
How many kilowats are in 1 amp?
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
How may watts in one ampere?
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
Relationship between language and power?
Language is a tool that can be used to assert power dynamics in society. The dominant group often sets the standards for language use, which can marginalize other groups. Control over language allows for the shaping of narratives, shaping people's perceptions, and maintaining power structures. Power can also dictate whose language is centered and valued in a given context.
What Effect does battery capacity on a circuits internal resistance?
Batteries are rated as ampere/hour any circuit that draws power from it effects it. The lower the internal resistance of the circuit the shorter the useful battery life as discharged.

How do you convert amp into watts?
Sneighke answered:Short answer, you can't. They are fundamentally different physical units.A Watt is a measure of power and the Amp (or Ampere) is a measure of current. For the relationship between the two, please refer to the related question.Different units cannot be equated to each other but can be combined with other units to produce the equivalents.------------------------------------------------------------------------------
What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
