SUMMARY
Current in electrical circuits is defined as the amount of charge (Q) that passes through a cross-sectional area per unit time (t), as expressed by the equation I = Q/t. The discussion clarifies that while current can be conceptually discussed at a point, it is fundamentally measured across a cross-sectional area. This distinction is crucial for understanding how current flows in conductors and is essential for accurate analysis in electrical engineering.
