AC Measurement

AC measurement refers to determining the voltage or current in an alternating current (AC) system, like household electricity. Unlike direct current (DC), which flows steadily in one direction, AC changes direction periodically. Measuring AC involves using a multimeter or similar device to capture the varying voltage or current over time. The measurement can be expressed as RMS (root mean square) values, providing an equivalent steady value that produces the same power. This helps electricians and engineers ensure electrical systems operate safely and efficiently, accurately assessing how much power is being delivered or consumed in AC-based applications.
