Course Description

Electrical measurement involves quantifying electrical parameters such as voltage, current, resistance, power, frequency, and energy. Voltage represents electrical potential difference. Current represents charge flow. Resistance determines opposition to current. Power indicates the rate of energy transfer. Frequency defines cycles per second in AC systems. Energy represents total power consumption over time. When performing measurements, engineers must understand several key performance indicators: Accuracy describes how close a measurement is to the true value. Precision refers to repeatability. Resolution defines the smallest change the instrument can detect. Sensitivity measures output change relative to input variation. Burden refers to the loading effect the instrument introduces into the circuit. Measurement errors fall into categories such as systematic errors, random errors, instrumental errors, and environmental influences. Temperature variation, electromagnetic interference, and poor connections all contribute to inaccurate readings. A professional engineer must not only record values but interpret them critically.
