# Current and Resistance

Current and resistance are fundamental concepts in the field of electricity and electronics. Current, represented by the flow of electric charge, is the foundation of all electrical phenomena. Understanding current is crucial for analyzing circuits, designing electrical systems, and troubleshooting faults. Resistance, on the other hand, opposes the flow of current and plays a pivotal role in determining the behavior of components within a circuit. Together, current and resistance form the basis of Ohm's Law, a fundamental principle that governs the relationship between voltage, current, and resistance in electrical circuits.
