DIDACTIC PROCESS AND MEANS FOR EVIDENCING THE LAW OF CONSERVATION OF ENERGY

摘要

Systems (100 and 500) are connected by a transmission (4, 4', 4') which drives at start the dynamic system (100), by the dynamotor (5) operating as motor, and is driven therefrom, when system (100) gives back any power to the dynamotor (5) operating as dynamo. Dynamotor (5) is also connected to a circuit (050). As motor the dynamotor (5) is connected to the net (51, 51'). The power supplied thereto is metered by meter (52), whose output (53') sends signals to comparator (54). As dynamo the machine (5) transforms the power received from system (100) and charges therewith a battery (59) through wires (58, 58'), meter (56) and wire (56'). Said meter output (54') sends the signals to comparator (54), which controls the power balance between energy from the net (51, 51') and energy given back to said battery (59), such balance being displayed by (55).
