On March 4, 2025, the 10th-grade students conducted an experiment in their Physics class. The topic of the experiment was "Demonstrating DC Voltage and Calculating DC Voltage Using a Multimeter." The activity was led by their teacher, Mrs. Rachana Pheng, at the American Intercon School, Sen Sok Campus. The purpose of this experiment was to demonstrate how to measure DC voltage and calculate DC voltage using a multimeter.

The experiment required essential materials such as a voltmeter or multimeter. During the experiment, the teacher demonstrated and explained the process in detail, after which the students were divided into groups to perform the experiment themselves. The students then collaborated in conducting the practical experiment under the guidance of the teacher and the lab assistant. The experiment proceeded smoothly and successfully achieved its intended objectives.
