Worcester Circuit Board

Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a baseboard. The connector system uses P.C.B. strips with cut-out sections whose ends can easily be inserted in spring terminals, ensuring low contact resistance and ease of connection. The kit consists of : 1 Baseboard, wooden, with spring terminals and three battery holders. 3 Batteries 10 Lamps 1.25 V M.E.S. 6 Lamp holders mounted on P.C.B. connectors. 10 Plain connector P.C.Bs 1 Wire wound potentiometer with crocodile clip connections. 1 Silicon diode. 1 Resistor 3.9 ohm 2.5 W. 1 pair Leads, red, with crocodile clip at each end 1 pair Leads, black, with crocodile clip at each end 1 pair Leads, yellow, with crocodile clips at each end. 2 Switches mounted on P.C.B. connectors. 1 PVC rod 15 cm long 2 Soft iron nails, 5 cm long. 2m Bare copper wire, swg 20. 2m Bare eureka wire, swg 34. 2m Plastic covered copper wire. 1 Electrode support. 10 Pencil lead electrodes. 1 Sheet copper foil, 150 mm square. 1 Pack Steel wool. 1 Instruction manual in English.
