What is 1 to the power of 0 equal to?
it would be equal to 1 only
Does 0.5 to the power of negative to equal 0.25?
No. 0.5 to any negative power would be greater than 1. 0.52 is equal to 0.25
A light draws current of 1.1 amps at 230 volts the power onput is 200w what is the circuit power factor?
The current's power factor is the true power divided by the apparent power. The Apparent Power is the volts multiplied by the amps. In this example, the ratio would be 200/253, or approximately .79.
What does 6 to the second power equal?
6 to the second power is 6x6 so that would equal 36! and 6 to the third power is 6x6x6 6 to the fourth is 6x6x6x6 just so u know
Which is greater 1kw equals equals KVA?
In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
A load of 9.41 kVA is equal to what in kW?
For a purely resistive load with a unity power factor, 9.41 kVA would equal 9.41 kW. However some equipment such as a motor will have a power factor less than 1. If the power factor is 0.8 then 9.41 kVA would equal 9.41 x 0.8 kW.
How many horsepower are there in 75kva?
It depends on the power factor. For a typical power factor of 0.92, 75kva would be equal to 69kw, which would be equal to 9.25 horsepower (electric motor).
What is the difference between unity power factor to 8 power factor?
Power factor does not go above 1. It is the cosine of the phase angle between voltage and current and, as such, can range between +1 and -1, although it should be understood that a negative power factor is mathematically equivalent to a generator - when looking at the load as if it is a motor - or vice versa. Unity power factor is applicable for a resistive load. A typical power factor for a big motor is about 0.92. A theoretical power factor of zero, corresponding to a phase angle of 90 degrees, would mean that the load is purely inductive or capacitive, and that the power supply and conductors are also ideal or theoretical.
What is the power factor of a DC system?
It would be unity, or 1.0. Since the voltage in a DC circuit does not vary with time, there can be no phase displacement of the current waveform, and therefore the current could not lead or lag the voltage waveform.
How much amps if heater element is 3000 watts and voltage is 220 and power factor is .80?
Heater elements usually have a power factor of 1, but if a load has a power factor of 0.8 it means that the VA is equal to the watts divided by 0.8, so that would be 3750 VA. With 220 v that would draw 17 amps.
Can a furnace operate on a power factor of 0.2?
If a furnace has a power factor not equal to 1 then there is a motor involved. If it was pure resistive element the Power Factor would be 1. That being said the motor can operate at .2 PF, but this is unusual and not very efficient. If this is the case I would expect that you have a bad motor control circuit and there may be a blown capacitor.
How many kva has 5000 watts?
There are zero watts in 700 volts.
Is the Nerf unity power system available in the UK?
The Unity Power System has become increasingly rare all across the world, so if you see it in the UK I would advise that you get before it is gone.
What circumstances would the greatest common factor be equal to numerator?
If the numerator was a factor of the denominator.
7 hp equals how much kva?
746 watts = 1 HP.Another AnswerTo some extent, you are trying to compare apples with oranges. A horsepower is simply the Imperial unit of measurement for power which, in SI, is measured in watts. So you can only convert horsepower to watts. There are 746 watts in one horsepower. The volt ampere is used to measure a different quantity, called 'apparent power', which is simply the product of the supply voltage and load current in an a.c. circuit. To convert apparent power to power (or 'true power'), you need to know a third factor, called 'power factor', which is the cosine of the angle by which the load current lags or leads the supply voltage.
What does achieve by unity mean?
"Achieve by unity" emphasizes the power of collective efforts. Its general gist is that together, people can accomplish more than they would individually.
Why is religious and ethnic tolerance so important for unity within Indonesia and Singapore?
Because without religious and ehtnic tolerance Unity within these countres would never occur and fighting would continue to happen. Because there is such diversity in these countries acceptacne of everyone is a crucial factor in maintaining unity.
