Ohm's Law

Ohm's Law is a fundamental principle in electronics that describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance, expressed as V = I × R (voltage equals current times resistance). This law is essential for calculating electrical values in circuits and is one of the most commonly used formulas in electronics design and troubleshooting. Understanding Ohm's Law allows engineers and makers to determine power consumption, select appropriate components, and ensure circuits operate safely within their electrical limits.
