Teaching Aids for Laboratory Courses in Electrical Circuits and Electronics

As more and more material becomes relevant for laboratory work in the undergraduate curriculum in electrical engineering, it becomes increasingly important to find more efficient systems for setting up the equipment for laboratory experiments. Any such system should result in a neat, easily followed arrangement when assembled, should be flexible with respect to the experiments which can be performed, and should not result in stereotyped experiments. This paper describes a system which has been evolved utilizing chassis upon which are mounted an array of banana jacks on three-quarter inch centers. Many different circuits can be assembled easily and quickly by plugging in components which are mounted on double banana plugs. Different chassis are arranged for different circuits such as a dual triode, single pentode, and push-pull power amplifier.
