The Worcester Circuit board allows students to construct and explore simple circuits series circuits parallel circuits and Ohm’s LawThe materials included in Worcester Circuit Board Kit enable a variety of circuits to be constructed quicklyStudents will explore concepts of electric circuits with the materials supplied. The kit consists of a baseboard with terminal connections a set of high-quality plastic connectors with metal inserts a potentiometer lamp holders bulbs and accessories.They will use a multimeter (not included - B8R06226) to measure voltage current and resistance through simple series and parallel circuits as well as compare these values through a light bulb and a resistor.Includes full experiment manual.Supplied with all accessories (does not include cells - B8R05412).This kit contains:1 x Electric circuit board: (L)330 x (W)330mm x (H)25mm.9 x Bulb holders1 x Bag of 16 bulbs2 x Push-button switches1 x Variable resistor (potentiometer)12 x Connecting bars1 x Resistor1 x Coil of wire 19 gauge copper1 x Coil of white wire 24 gauge copper1 x Coil of steel wire 28 gauge2 x Red connecting wires2 x Black connecting wires2 x Alligator clips1 x Container of graphite rods1 x Bag of steel wool1 x Set of instructions
