we know that phasor voltage, current and impedence can be represented by vector. we know phasor v is equals to the product of phasor i and impedence. the what is the process of multiplication? is it dot or cross product?
Phrak said:I have no idea. Do you know how to multiply complex numbers? If I wanted the voltage as a function of impedence and current. I would express impedence, current and voltage as complex numbers.
sabbir ahmed said:if complex number can be measured like a vector then why complex multiplication is not dot or cross?
A phasor is a complex number that represents the amplitude and phase of a sinusoidal voltage or current. It is typically represented by an arrow in a complex plane, with the length of the arrow representing the magnitude and the angle representing the phase difference.
Phasor voltage is a complex number, while regular voltage is a real number. Phasor voltage takes into account both the magnitude and phase of a sinusoidal voltage, while regular voltage only represents the magnitude.
Phasor voltage and phasor current are related by Ohm's law, where the phasor voltage is equal to the product of the phasor current and the impedance of the circuit. This relationship allows us to analyze AC circuits using phasor notation.
Phasors are used in electrical engineering to simplify the analysis of AC circuits. By converting sinusoidal signals into phasors, we can use algebraic equations to solve for voltage and current values, rather than using complex calculus. Phasor analysis is commonly used in power systems and electronics.
Yes, phasors can be used to analyze non-sinusoidal signals by using a technique called Fourier analysis. This involves breaking down the signal into its component sinusoidal waves and representing each with a phasor. The sum of these phasors will then accurately represent the original non-sinusoidal signal.
