Relation between active power plus reactive power plus apparent power?
Apparent Power=Active Power+Reactive Power or Active Power=VI Cos(Phase Angle) Reactive Power=VI Sin(Phase Angle) Apparent Power= VI
Is there any active or reactive power in dc current?
Active, yes; reactive, no.
How to increase load on a bus in power system.Does it means to increase the bus active power demand or reactive power demand or both?
You can increase load on a bus power system by increasing the bus active power demand ans reactive power demand.
Why is the total active power of a network always the sum of the individual active powers regardless of series or parallel connection of components?
The total active power in a network is the sum of the individual active powers because active power represents the rate at which energy is consumed or converted into useful work. In both series and parallel configurations, all components draw from the same source, ensuring that the total energy supplied is equal to the sum of the energy consumed by each component. This principle holds true regardless of the arrangement because power is additive in electrical systems. Thus, the overall active power is simply the collective contribution of all components in the network.
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
What is an active power?
An active power is the real component of the power of an alternating current circuit.
Relation between active power plus reactive power plus apparent power?
Apparent Power=Active Power+Reactive Power or Active Power=VI Cos(Phase Angle) Reactive Power=VI Sin(Phase Angle) Apparent Power= VI
What was Phoebe's first active power?
Phoebe's first active power on Charmed was the power to levitate.
What does a negative active power means?
Let see an example. The active power absorbed by an AC motor is used to produce mechanical power delivered on the output shaft. If the mechanical power is negative (the motor is pushed to work as a brake) the active power 'absorbed' is also negative. The motor converts the mechanical power in active electrical power delivered in the electrical network. Any AC generator is supplied with negative active power, or it deliver to the network positive active power.
What does active output mean?
Electricity has three terms. Active power - Watt. Apparent power VA, reactive power VAR. Watt is known as active output
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 )
What is the Difference between active and apparent power?
Active power is the real power consumed by an electrical device to perform work, measured in watts (W). Apparent power is the combination of active power and reactive power, measured in volt-amperes (VA). Apparent power represents the total power that is supplied to the system, while active power represents the actual power consumed by the system.
'' active transducer donot required power source for operation''?
No, active transducers require a power source for operation.
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.
Is there any active or reactive power in dc current?
Active, yes; reactive, no.
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)
Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
