The Consulab CL-1910 Electrical Fundamentals trainer has been designed as an aid in teaching electricity while working through a set of introductory experiments. All the experimental components are kept in a steel cabinet divided in two sections. These can be swung open on a hinge to provide a large work space when the experiments are in progress. The components used in the experiments, -- resistors, capacitors, coils, switches, etc. -- are mounted on clear plastic Moduponents®. These are marked with the component symbols and can readily be installed in groups in the trainer case, as required for a particular experiment.
