Why do we use phasor representation in physics..For example,why we need maxwells equation in phasor form as well??
Abel I Daniel said:ok ,thank you for the reply...what made me ask this question is-i saw maxwells equations(electromagnetic) written in phasor form from dpoint form by just substituting d/dt with jw..So what my questin is ,what is the implication of removing that time factor from that equation??
A phasor representation in physics is a mathematical tool used to represent the amplitude and phase of an oscillating quantity, such as a wave or electric current. It is a complex number that combines the magnitude and phase angle of the oscillation into a single quantity.
Phasor representation is used in physics to simplify the analysis of oscillating systems. It allows us to treat the amplitude and phase of the oscillation as a single variable, making it easier to solve problems involving waves or alternating currents. It also allows us to use the techniques of complex numbers to solve these problems.
There are several advantages to using phasor representation in physics. Firstly, it simplifies the analysis of oscillating systems by reducing the number of variables involved. Secondly, it allows us to use the techniques of complex numbers to solve problems, which can often make the calculations easier. Lastly, it helps to visualize the behavior of oscillating systems by representing them as rotating vectors in the complex plane.
While phasor representation is a useful tool in physics, it does have some limitations. It can only be applied to linear systems, meaning that the amplitude and phase of the oscillation cannot change in a non-linear manner. Additionally, it cannot be used to analyze systems with time-varying parameters.
Yes, phasor representation can be used in other fields besides physics. It is commonly used in electrical engineering to analyze alternating currents and in signal processing to analyze waves and vibrations. It can also be applied in other areas such as acoustics, optics, and mechanical engineering to analyze oscillating systems.
