You won't find an easier way to demonstrate the principles behind electric circuits than with this clever unit designed by teacher Daniel D'Arcy. -- The Circuit Board can be used to study Ohm's law, series/parallel circuits, and the relationships between current, resistance, voltage, power, and energy. Your students will clearly see the change in brightness of the bulbs as different circuit configurations are explored. It is constructed of flame-retardant materials and has a carrying handle and protective cover panel. -- The demonstrator comes with 12-adaptors, 2-fuses, 5-different wattage light bulbs, 10-resistance labels, and a 28-page teacher's manual, all supplied in a handy storage box. Measures 42 cm x 64 cm x 6 cm. |
