A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Pf of a load?

Pf is the symbol for Power Factor.

How many watts are in 40VA?

The formula you are looking for is W = I x E x pf. (pf = power factor).

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.

What is difference between 0.8 leading and 0.8 lagging power factors?

Power factor measures the phase difference between voltage and current. If they are in phase the Power Factor is one. If the current and voltage are out of phase the power factor is between zero and one. You can describe the PF by saying the current lags the voltage with a PF = .8 or the voltage leads the current with a .8 PF.

What is the physical difference between 0.5 pf lead and 0.5 pf lag how they play their different roles in an electric cicuit?

0.5 lead PF or Power Factor means that the signal is ahead of the input voltage by a factor of 90 degrees. The lagging PF means it falls behind the input signal. In sinusoidal signals 0.5 lead or lag will be the same.

What happens when lagging Power Factor changes to leading PF?

when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.

Why use power factor meters?

To determine and correct PF to unity. Leading or lagging PF costs money to businesses correcting PF usually to 0.99 is an efficiency drive

How do you convert MVA into MW?

You would have to know the Power Factor, normally designated PF. MVA x PF = MW. If the PF is unity then MVA = MW. A PF of UNITY suggest the load is purely resistive with neither capacitive nor inductive components in the load or source. Of course this can mean such components have been balanced artificially.

How kVA do you need for 75kW motor?

It depends on the power factor. If the PF = 1, then you need 75kVA. In general, kVA needed = 75kW/PF.

How many watts will be produced using 200 amps at 110 volts?

Watts are the product of amp x volts. 200 x 110 = 22000. The above is correct for a pure resistive load. With an inductive load the formula is Watts = Volts x Current x PF Where PF = Power factor which is between 0 and 1. For definition of Power Factor, search

How does power factor correction solve the problems caused by inductive loading?

You calculate power by multiplying voltage x current x Power Factor (PF). PF = 1 for a resistive load so you essentially convert maximum power with a resistive load. With an inductive load the PF decreases from 1 toward zero. Hence the lower the power factor the less efficient the system. This reduced PF is caused by the current and voltage sine waves being out of phase. If they are 180 degrees out of phase you have zero PF. PF correction involves circuitry that basically helps "tune" the circuit to reduce the lag. Capacitors are involved heavily in this process to tune the circuit.

What is the formulae for a 3 phase circuit to calculate the power?

Watts = Amps x Volts x 1.73 x pf. pf is the power factor.

How many kva is 21000 kw?

KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.

How do you calculate 3 phase power with a power factor?

The formula you are looking for is kW = amps x volts x 1.73 x pf / 1000. where kW means 'kilowatts' and pf means 'power factor'.

20KW machine 480 volts 3 phase what is the amps?

The formula you are looking for is Amperage = kw x 1000/1.73 x Voltage x pf. pf is power factor. Use .9 as a reference for 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 do you calculate gas pressure from 14.73 to 14.65 pressure base?

How many watts in 1000va?

This conversion is dependant of power factor. Kw = kVA x PF. So assuming 0.8 pf it'l be 800 watts

How many kilowatts equals to one ampere?

To answer this question a voltage and pf (power factor) must be stated. kW = I x E x pf/1000.

How to calculate KW from full load amps and volts?

Single phase formula for you to use kW = I x E x pf/1000. Three phase kW = I x E x 1.73 x pf/1000. pf = power factor. Use .9 for pf and the answer will be close.

What is the product pf prime number of 69?

69 = 3 x 23

How do you know the required power factor?

Power factor (PF) varies between 1 and zero. It is 1 for a pure resistive load. The closer to one the more efficient the system. Hence the ideal is to get PF to one. This isn't possible with an inductive load which causes current and voltage to be out of phase. Various circuits are used to try and correct PF to 1 to increase efficiency.

What is the Phase difference between voltage and current values?

The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.
