In this paper, we use the tools available in the simulink library in MATLAB software to design two sets of virtual experiment which support the teaching and learning process in high school. Two sets of virtual experiment a resistor bridge circuit and a rectified current circuit were designed. The advantage of the two sets of virtual experiment is simple in design, easy to conduct experiments and observe in the classroom. These advantages open up great hopes for replacing real experiments that are often cumbersome, time-consuming and laborious to prepare before class. Moreover, virtual experiments also support teachers to be able to perform many experiments with different physical conditions in a short time. This will help teachers have the opportunity to convey a lot of knowledge to learners.Trong bài báo này, chúng tôi sử dụng các công cụ có sẵn trong thư viện simulink của phần mềm MATLAB để thiết kế hai bộ thí nghiệm ảo (TNA) nhằm hỗ trợ tiến trình dạy và học ở trường trung học phổ thông (THPT).
