How do you calculate active power of 250mva and power factor of 95?

.25 x .95 = .2375 watts = 237.5 milliwatts
Power factor has a maximum value of 1, so I assume you meant .95
CommentOnce again, we have questions that use the wrong symbols for electrical units, leading to confusion.
In 'mva', 'V' and 'A' should both have been capitalised, so it is reasonable to assume that 'M' should have been capitalised, too! So what the questioner probably really means is 'MV.A' (megavolt amperes), not mV.A (millivolt amperes)!
So the answer the writer is probably looking for is 237.5 MW (megawatts).

If a load takes 50 kW at a power factor of 0.5 lagging Calculate the apparent power and reactive power?
If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA
Introduction to power and power factor?
The power is the product between the magnitude of voltage and the magnitude of current. Whereas the power factor is a ratio between the active power and the apparent power.
How do you find whether it is inductor or capacitor if only power factor is given?
in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.
What is the active power consumed by pure capacitive reactance?
There is no 'active' power in a purely capacitive load. Active power is the result of the supply voltage multiplied by the in-phase component of the load current. In a purely capacitive load, the load current leads the supply voltage by 90 degrees and, so, there is no in-phase component and, hence, no active power.
What is cos on an electric motor?
Cos phi is a European term used on a motor to differentiate between apparent power (kVA) of an inductive load as compared to the active power (kW) that is really used by the load. Cos phi= active power/apparent power. In North America a more familiar term would be power factor. Power factor = kW/kVA

Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
What is powerfacter?
The ratio of active power (real power) and apparent power is called power factor ( pf ). Power Factor ( pf ) = Active Power / Apparent Power = .................. ( kvar )
How calculate the power factor?
p.f=kW/kV.A
How do you calculate power factor kvr?
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
Introduction to power and power factor?
The power is the product between the magnitude of voltage and the magnitude of current. Whereas the power factor is a ratio between the active power and the apparent power.
What is the formula of active power?
For a single-phase system, active (or 'true') power is the product of the supply voltage, the load current, and the power factor of the load.
What is the power factor when the apparent power is 150 VA and the active power is 100 W?
The equation for power factor is PF = True power in watts/Apparent power in Volt Amps.
How do you calculate power load given kva?
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
How do you find whether it is inductor or capacitor if only power factor is given?
