Which of the following physical quantities is defined as the rate of flow of electric charge?
A. Electric potential
B. Electric current✓ Correct Answer
C. Electric resistance
D. Electrical conductance
💡 Solution & Explanation
Electric current is fundamentally defined as the rate of flow of electric charge per unit time across any cross-section of a conductor, measured in amperes. Alternative options represent distinct electrical properties like potential difference or opposition to flow rather than charge transit rates.
