quick overview :

Worcester Circuit Board Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a base board. 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 connectlon. The kit consists of : 1 Baseboard, plastic. 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 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.
