Answer
Ohm's Law is used to design, analyze, and troubleshoot electrical circuits. It helps engineers calculate the correct resistor values, determine power requirements, size wires appropriately, and diagnose circuit problems. Whether you're building a simple LED circuit or complex electronic equipment, Ohm's Law provides the mathematical foundation for safe and effective circuit design.
