How To Measure Voltage

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.

Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).

Learn the fundamentals of creating an AC or DC voltage measurement system. See how to properly connect the signals to your data acquisition system for accurate acquisition.

This document is part of the How-To Guide for Most Common Measurements centralized resource portal.
