Electrical resistance measurement

Electrical resistance measurement assesses how much a material or component opposes the flow of electrical current. It is measured in ohms (Ω). To determine resistance, a small known current is applied, and the resulting voltage drop across the object is measured. Using Ohm’s Law (Resistance = Voltage / Current), we calculate its resistance. This measurement helps evaluate the material's quality, integrity, or performance, and is essential in designing and troubleshooting electrical and electronic systems, ensuring components operate safely and effectively.
