The angle through which max power is genereated is called beam width?

Sounds like you're talking about the main lobe of a radio antenna.
It's kind of sloppy to say that the "max" extends across some width, since the "max"
only happens in one single, specific direction.
The "beam-width" is also often referred to as the "3dB beam-width". It's the angle between
the two points where the power is 3 dB less than the max ... one point on each side of the max.

What is conduction angle in SCR?
The conduction angle in an SCR is the phase angle relative to the power line at which point the gate is fired to commit the anode to conduct to the cathode. By varying the conduction angle, you can change the average power transferred by the SCR.
What theorem has a to the second power plus b to the second power plus c to the second power?
The theorem you are referring to is a2+b2=c2 which is called the Pythagorean theorem. This describes the side lengths of a right triangle in which the two sides that meet at a right angle are sides a and b respectively and side c is the hypotenuse.
What is the power number called?
It is called the "exponent".
How do you measure an angle of a power polygon?
You mean a power polygon right? I'm going to assume you do since poluyon isin another language that I don't know... You use a protractor, like you do withnormal polygons... but they are used more as a tool to learn what is obtuseand acute angles are that the angle itself...And for those who don't know what a power polygon is check this out: What_is_a_power_polygon
What is the rate at which work is done called?
Power
What affect the phase angle?
Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.
Why is power factor is cos of angle between voltage and current?
Power factor is the ratio of true power to apparent power -if you refer to the so-called 'power triangle', these correspond to the adjacent and hypotenuse of a right-angled triangle. The cosine of the angle between them is the ratio of hypotenuse (apparent power) to adjacent (true power). As the power triangle is derived from the voltage/current phasor diagram, this is exactly the same angle as that between load current and supply voltage.
What is Relation between loss angle and Power factor?
Power factor = cos (angle)PF=cos @
What is meant by Generator P.f?
the cosine of the angle between voltage and current of generator is called power factor (pf) of generator.
Why it is power fector of cos?
Power factor is the ratio of the angle between the voltage and current.In the power triangle cosine angle is the ratio between them...
What is the physical meaning of power angle in a power system?
a curve drawn for power against load angle maximum power occurs at load angle of 900 maximum power will be transffered from sending end to receiving end when the reactance is 1.732 times its reactance
What do you understand by the term phase angle?
The phase angle is the angle by which a load current leads or lags the supply voltage. The cosine of this angle is called the power factorof the load.The terms, phase indicating logical and systematic, and angle indicating radial ordinance. Phase angles indicate instances varied by distance and magnitude. A rational occurence, quantum in nature. Power factor values derived from metadata express velocity/magnitude traits.
What are the perfect angles and powers for bow chief?

What is conduction angle in SCR?
The conduction angle in an SCR is the phase angle relative to the power line at which point the gate is fired to commit the anode to conduct to the cathode. By varying the conduction angle, you can change the average power transferred by the SCR.
Why power factor using cos theta angle?
It's actually cos phi, where the Greek letter, 'phi', is the symbol for phase angle -the angle by which a load current lags or leads the supply current in an a.c. system (the Greek letter, 'theta', is used for the displacement of instantaneous values of current or voltage from the origin of a sine wave).The reason why power factor is a cosine requires you to understand the relationship between apparent power, true power, and reactive power. Apparent power is the vector sum of true power and reactive power, and can be represented, graphically, by the so-called 'power triangle'. In the power triangle, true power lies along the horizontal axis, reactive power lies along the perpendicular axis, and the apparent power forms the hypotenuse, and the angle between true power and apparent power represents the phase angle. By definition, power factor is the ratio between true power and apparent power, and this ratio corresponds to the cosine of the phase angle.From this, we can conclude that true power = apparent power x cos phi, where 'cos phi' is the 'factor' by which we must multiply apparent power to determine true power -i.e. the 'power factor'.
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 is the government where the power is held by people and exercised through elected representative called?
