Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
Can reactive power measure by 2 wattmeter method?
Active volts amperes are measured by 2 wattmeter methods. A wattmeter will measure active power and not reactive power. Electrical engineering is a promising career for anyone who likes to generate power.
What is the formula for power delivered by a voltage source?
Power is voltage times current.
How can convert active power to reactive power and apparent power too?
'Active' power describes the rate at which energy is delivered to a load and is permanently lost, and is expressed in watts. 'Reactive' power describes the rate at which energy is alternately stored within a magnetic or electric field and returned to the supply every quarter-cycle, and is expressed in reactive volt amperes.You cannot 'convert' one to the other.'Apparent' power is the vectorial sum of active power and reactive power, and is expressed in volt amperes.
What is the formula of load calculation?
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.
When a formula is in an active cell the underlying formula is visible in the what Formula Bar or Worksheet or Status bar or Name Box?
If there is a formula in the active cell, then the formula will be displayed in the formula bar and the result of the formula will appear in the cell.
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 is formula of power?
the formula for power is work/time.
Where does the contents of the active cell appears?
The formula bar.
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 display the contents of the active cell?
formula bar
What allows the user to enter or edit the value or formula contained in the active cell?
The formula bar.
What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
