How is the direction of current flow usually indicated in schematics?

In schematic diagrams, the direction of current flow is typically indicated using arrows. These arrows visually represent the path that electrical current takes through the circuit, making it easier for the viewer to understand how the circuit operates. The use of arrows is a standard practice in electrical engineering and provides a clear and intuitive way to convey this important aspect of circuit analysis and design. By following the arrows, technicians and engineers can trace the flow of electricity, troubleshoot issues, and design circuits with a clearer understanding of current paths. This practice aligns with conventional symbols and legends used in engineering, ensuring clarity among those who read and interpret the schematics.
