feszültségkoordináták

feszültségkoordináták is a specialized term used in Hungarian language literature to describe the representation of voltage in a coordinate system, often in the context of alternating current (AC) circuit analysis. The concept is analogous to complex phasor representation, where each voltage is expressed as a vector in a two‑dimensional plane. In this plane the horizontal axis traditionally represents the real part (in‑phase component), while the vertical axis carries the imaginary part (quadrature component). Pacifically, a sinusoidal voltage of the form V(t) = Vm·cos(ωt + φ) can be depicted as a vector of magnitude Vm pointing at an angle φ relative to the horizontal axis.

The coordinate choice has practical advantages. By treating voltage as a point in a plane, circuit equations become algebraic rather than differential; Kirchhoff’s laws can be applied to vector sums, and complex impedance can be added straightforwardly. Educational textbooks often introduce feszültségkoordináták as an intermediate step between time‑domain differential equations and frequency‑domain analysis used in engineering practice.

In engineering contexts, the most common form of representation is the polar coordinate version, where a voltage is given as (|V|,∠θ). However textbooks sometimes maintain a rectangular view (Vx, Vy) to emphasize the geometric interpretation of phase shifts. According to Hungarian norms, these coordinates are typically written with the module first, followed by the angle in degrees or radians.

Overall, feszültségkoordináták facilitate the visualization of AC waveforms, simplify the calculation of power, reactance, and impedance, and provide a unified language for communicating phase relationships in electrical networks.
