potential difference

[pəˈtenʃəl ˈdɪfərəns]
nounpl: potential differences
diferença de potencial
1. The difference in electric potential between two points in an electric field, measured in volts; the work done per unit charge in moving a charge from one point to another
The potential difference across the resistor is 10 volts.
A diferença de potencial através do resistor é de 10 volts.
2. In electrochemistry, the voltage difference between two electrodes in an electrochemical cell
The potential difference in the battery determines the current flow through the circuit.
A diferença de potencial na bateria determina o fluxo de corrente através do circuito.
This is a fundamental concept in physics and electrical engineering education worldwide. In Brazil, the term 'diferença de potencial' is the standard academic translation, while 'tensão' (tension/voltage) is more commonly used in industrial and practical electrical applications. The concept is taught identically in both Brazilian and American schools, making it a universal scientific term.
