phase angle
[/feɪz ˈæŋɡəl/]
nounpl: phase angles
ângulo de fase
1. The angular measure of the difference in phase between two periodic quantities or between a periodic quantity and a reference point, typically measured in degrees or radians
The phase angle between voltage and current in an AC circuit determines the power factor.
O ângulo de fase entre a tensão e a corrente em um circuito de CA determina o fator de potência.
2. In signal processing, the angle representing the position of a sinusoidal wave at a specific point in time relative to a reference wave
By adjusting the phase angle, engineers can synchronize two signals.
Ao ajustar o ângulo de fase, os engenheiros podem sincronizar dois sinais.
3. The argument of a complex number in polar form, representing the angle from the positive real axis
The phase angle of the impedance affects the circuit's response.
O ângulo de fase da impedância afeta a resposta do circuito.
This is primarily a technical term used in electrical engineering, physics, and signal processing contexts in both Brazil and the USA. It is essential terminology in STEM education and professional engineering fields. The term is consistent across both regions with minimal variation, reflecting the universal nature of scientific terminology.
