How is instantaneous energy measured?
Instantaneous energy can be measured by calculating the power of a system at a specific moment. This can be done by measuring the rate of energy transfer or by using a power meter. The unit of measurement for instantaneous energy is typically in watts or joules per second.
What is the formula to calculate the instantaneous power in an electrical circuit?
The formula to calculate the instantaneous power in an electrical circuit is P V x I, where P represents power, V represents voltage, and I represents current.
What is the instantaneous power formula in physics and how is it calculated?
The instantaneous power formula in physics is P Fv, where P is power, F is force, and v is velocity. It is calculated by multiplying the force acting on an object by its velocity at a specific moment in time.
What is mean by instantaneous release of current in mpcb?
Instantaneous release of current in an MPCB (Motor Protection Circuit Breaker) refers to the rapid tripping of the circuit breaker when a fault current exceeds a predetermined threshold. This feature provides quick protection to the motor by disconnecting it from the power source to prevent damage.
What is the instantaneous power equation and how is it used in physics?
The instantaneous power equation is P Fv, where P is power, F is force, and v is velocity. This equation is used in physics to calculate the rate at which work is done or energy is transferred at a specific moment in time. It helps determine how much power is being exerted by a force on an object in motion.
What is instantaneous power factor?
Instantaneous power doesn't have a frequency; it's instantaneous!
What is powerful mean?
The product of the instantaneous voltage and the instantaneous current for a circuit or component.

What is average power?
average power is the average of all the instantaneous values during one alternation..
What is an kilowatt meter?
A device used to indicate instantaneous power usage.
What do you mean by instantaneous speed?
Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
What does instataneous mean?
You mean instantaneous - means happening or completed in a moment, with no delay, immediate
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.

What is the unit for average power?
Same as for instantaneous power or any other kind of power:Watt(same as joule per second)
