Educational system about the generation and consumption of electric energy

An electric energy teaching aid to be connected to a plurality of different energy source comprising:

• a housing;
• handles attached to the housing to carry the housing by hand;
• a plurality of an electric light bulb, as a means to gauge the energy generated by the energy source connected to it, each of which attached to a lamp socket;
• a plurality of said lamp socket, each of which is attached to the housing and arranged in a multitude of identical rows, each row has the same number of lamp sockets;
• a plurality of an on/off switch, each of which is attached to the housing and electrically connected to said electric light bulbs, as a means to interrupt the electric energy flow to each of said electric light bulb,
• a plurality of an electric energy conversion device, each of which attached to the housing and electrically connected to said light bulbs, as a means to convert an unregulated electric voltage and current form of an electric energy source into a constant electric voltage and current form that is rated to feed said electric light bulbs;
• a plurality of an electrical receptacle, each of which is attached to the housing and electrically connected to said electric energy conversion device, as a means to electrically connect with a plurality of said electric energy sources.
