zero potential difference
[/ˈzɪroʊ pəˈtenʃəl ˈdɪfərəns/]
nounpl: zero potential differences
diferença de potencial zero
1. An electrical condition where two points have the same electric potential, resulting in no voltage between them
When the voltmeter reads zero potential difference between the two terminals, no current will flow through the circuit.
Quando o voltímetro lê uma diferença de potencial zero entre os dois terminais, nenhuma corrente fluirá através do circuito.
2. In physics, a state where the electric field strength between two points is null, indicating equipotential surfaces
The conductor in electrostatic equilibrium maintains a zero potential difference throughout its interior.
O condutor em equilíbrio eletrostático mantém uma diferença de potencial zero em todo o seu interior.
This is a fundamental concept in electrical engineering and physics education. In Brazil, it is taught as part of the standard curriculum in technical schools and universities. The term is used across both Brazilian and European Portuguese technical contexts without significant variation, reflecting the international nature of scientific terminology.
