- Kirchhoffs laws in phasor domain - Physics Stack Exchange
While analysing AC circuits, we write voltage, current etc all with complex numbers namely "phasors" While studying the same, I wondered if Kirchhoff's laws held good with current and voltage in t
- Phasor form of Maxwells Equations - Physics Stack Exchange
I'm interested in the transformation from the standard Maxwell's equations to their phasor equivalents From the literature, this means injecting: \begin {equation} E = Re (\boldsymbol {E}e^ {j\omeg
- Where is the Phasor Form of Maxwells Equations used?
I've studied and understand the differential and integral forms of Maxwell's equations, and understand the basic math and logic behind phasor notation for circuit analysis Still, I'm confused as t
- Voltages phasors in AC circuit - Physics Stack Exchange
The following involves phasor notation, which is in the frequency domain You need to add ac voltages vectorially for RC and LC circuits because the voltage and currents in inductors and capacitors are 90 degrees out of phase with each other, whereas the voltage and current are in phase for a resistor
- homework and exercises - Finding frequency from phasor in EM wave . . .
Here’s a homework question from my class on electromagnetism: The electric field phasor is E = E0[3 cos x sin 2y, 6 sin x cos 2y, j5 sin x sin 2y]e−3jz E = E 0 [3 cos x sin 2 y, 6 sin x cos 2 y, j 5 sin x sin 2 y] e 3 j z What is the frequency f f, where f = ω 2π f = ω 2 π? From looking in the lecture notes and on Google, it seems like there is no way to determine frequency when
- Why do phasors add like vectors? - Physics Stack Exchange
A proper answer to this question should explain why phasors work in the first place (i e because the equations in question are linear and time invariant) From there, it's trivial to show why phasors add like vectors
- Description of phasor form of Maxwells equations in linear media
The phasor representation accounts for this phase shift by the complex form of ϵ ϵ and μ μ ϵ ϵ is the complex permittivity of the medium, and μ μ is the complex permeability of the medium
- Phasor Notation Convention - Which Projection to Consider?
A phasor is a rotating vector If, at time t it makes angle (ωt + ϕ) (ω t + ϕ) with the x axis, its projection (for a phasor of unit magnitude) on to x axis is, by definition, cos(ωt + ϕ) cos (ω t + ϕ), and its projection on to y axis is sin(ωt + ϕ) sin (ω t + ϕ) Which of these we choose to represent a sinusoidal displacement, voltage or whatever is pretty arbitrary Whether
