In this paper we describe the effect of using Virtual lab for electronic circuits, namely, DoCircuits on the circuit design and analysis skills of second year engineering students of Electronics and Telecommunication program. We present the results of a control group-experimental group study. As part of the study, the students performed two experiments using Virtual labs along with hardware. Experiment design guidelines given in the online SDVIcE too are used. This was followed by a post-test, end semester laboratory examination, survey and interviews. The analysis of students’ scores in the laboratory examination and post-test indicate an improvement in the circuit design and analysis skills of students. The results of the survey and interviews indicate that the students perceive that performing experiments using the Virtual lab helped them in conceptual understanding and improving their circuit design and analysis skills due to the various affordances provided by the Virtual lab.
