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, 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.
• 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.
