What terminology describes the effect of a reactive load in a circuit and the change of the voltage-current timing relationship?
The terminology that describes the effect of a reactive load in a circuit is "phase shift." In circuits with reactive components like inductors and capacitors, the voltage and current do not peak at the same time; instead, they are out of phase. This results in a timing relationship where the current either leads or lags the voltage, depending on whether the load is inductive or capacitive, respectively. This phase difference can affect the overall power factor of the circuit.

What is the relationship of the reactive volt-amperes to the total volt-amperes in a unity-power factor circuit?
If you have unity power factor, p.f.=1, then the real power P must equal the total power S. Therefore, there is no reactive power being used, Q=0.Alternative AnswerApparent power is the phasor (vector) sum of true power and reactive power: (apparent power)2 = (true power)2 x (reactive power)2
What is the electrical term VAR?
Seeing as how this question is under Home Electricity the term VAR stands for Volt Amps Reactance.See related links belowVAR is a term for computer distribution business. Which stands for Value Added Retailer.
Breifly explain about reactive power in electric circuits?
Reactive power is opposite to Active power. The vector sum of these two powers is apprant power. So reactive power is vector difference between Apprant power & actual power given by Reactive power= Root of (difference between squares of apprant & active power). It is lost power of the system on which power factor depends.
Why reactive power is so confusing for engineers?
This is because reactive power concept is completely different from active(real) power,That is when we talk about active (real) power, we deal with two terms :The average value, and the instantaneous value.Both has significant values; let's say the average value is 5kw, where the instantaneous value maybe 2kw or 6kw, etc...On the otherhand, reactive power has always a Zero average value, and a different significant instantaneous values, but since the instantaneous value is difficult to measure, we always take the maximum instantaneous value of reactive power and deal with it as a textbook terminology (Reactive power) which is symbolized as Q and equals V I sintheta.And for the same reason (difficult to measure instantaneous value ) we easily deal with the average value of the active power other than the instantaneous value.As a brief:(Active power) symbolized P or known sometimes as real power equals V I cos thetarepresents the average value.(Reactive power) symbolized Q equals V I sin theta represents maximum instantaneous value.Someone can ask!Why not to take the maximum instantaneous value of average power such as reactive power as a terminology?Easily , why not to unites the two concepts ?!This is the answer of our main question (Why reactive power is so confusing for engineers?)This is easily because ,there is no useful meaning of using the instantaneous value for the active power, because it is a real produced power goes in one direction from source to load, where the average reactive power is always zero valued, since it goes back and forth in the network, and we are forced to deal with it in some way as an indication value and give it a unique terminology to express it as a fact that we cannot skip.In other words, you cannot compare two different things; apple and banana! Each one has a different taste.I hope that I answered the question, and dislodged some dust about this confusing concept, even I didn't take the boring mathematical path.
Why reactive power is named as reactive?
Actually reactive power is a power which flows in between load to source which is a reactive action of the power given from source to load.the given power to load will not be utilised fully.some power will be oscillating from load to source.this is called reactive power.

The more reactive substance is known as a catalyst.
What term describes the most reactive nonmetals that have seven valence electron?
halogens
What term describes the reactive nonmetals that have seven valence electrons?

What is it called when a property that describes the way a substance acts with another substance?
Chemical and physical properties
What term describes the most reactive non metals that have 7 valence electron shields?
They are basically called halogens.
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 are some strategies for maintaining a healthy relationship when married to someone with Reactive Attachment Disorder?
When married to someone with Reactive Attachment Disorder, it is important to establish clear communication, set boundaries, seek therapy together, practice patience and understanding, and prioritize self-care to maintain a healthy relationship.
What is the relationship between voltage instability and reactive power?
Voltage is a function of reactive power becouse normally X is greater than R between 2 nodes, so the voltage of a line is determined by X, wich on the other hand depends from reactive power Q
Is very reactive a physical or chemical property?
"Very reactive" is a chemical property because it describes how likely a substance is to undergo a chemical reaction with other substances. It does not pertain to any physical characteristic of the substance.
What is different between active power and reactive power?
'Active power' describes the rate at which energy is dissipated by a circuit through heat transfer, or (e.g. in the case of a motor) provides useful work. 'Reactive power' describes the rate at which energy is alternately stored within an electric or magnetic field and, then, returned to the supply every quarter-cycle.
