STUDENT Kit - Electricity

Description Set of apparatus for carrying out 28 fundamental student experiments on electricity. Stored in a tough Gratnells tray with foam inlay featuring recesses moulded to the shape of the apparatus and covered by a transparent lid. Circuits are assembled using components in plug-in housings plugged into a plug-in board. Power is supplied via 2 D-cell, LR20, 1.5 V batteries (batteries not included) or via an external power supply. Includes instructions for 28 experiments on electricity: · Simple electric circuits (2x) · Electrical conductors and insulators · Production of heat and light · Various sources of electricity *) · Conduction in liquids *) · Single-pole change-over switches (SPDT) · Two-way switches · Measurement of current in a simple electric circuit **) · Measurement of voltage in a simple electric circuit **) · Incandescent lamps connected in series · Incandescent lamps connected in parallel · Terminal voltage and open-circuit (no-load) voltage **) · Batteries connected in series and parallel **) · Battery made from a lemon **) · Relationship between voltage and current determined by varying voltage *)**) · How electrical power depends on other variables in an electric circuit *)**) · How electrical work depends on other variables in an electric circuit *)**) · Ohmic resistance *)**) · How electrical resistance depends on temperature (2x) *)**) · How electrical resistance depends on the length of the wire *)**) · How electrical resistance depends on the cross section of the wire *)**) · How electrical resistance depends on the material of the wire *)**) · Resistivity *)**) · Resistors connected in series *)**) · Resistors connected in parallel *)**) · Variable resistors · Potentiometers *)**) 1021091 AC/DC power supply, 0 - 12 V, 3 A (230 V; 50/60 Hz) or 1021092 AC/DC power supply, 0 - 12 V, 3 A (115 V; 50/60 Hz) (for experiments marked *) Analogue Multimeter (for experiments marked **) Includes: 1 Plug-in Board for Components 2 Battery Holders 1 Set of Conductors and Non-Conductors 1 Set of 10 E10 lamps 1.3 V, 60 mA 1 Set of 10 E10 lamps 3.8 V, 300 mA 3 E10 lamp sockets 2 Change-over switches 1 Toggle switch, single pole 1 Push-button (NO), single pole 1 Roll of chrome-nickel wire 1 Roll of constantan wire 1 Roll of iron wire 1 Set of 10 connecting plugs 6 Connecting plugs, 4 mm 6 Crocodile clips 1 Potentiometer, 220 ? 1 Linear Resistor, 47 ?, 2W 2 Linear Resistors, 100 ?, 2W 2 Zinc plates 2 Copper plates 2 Carbon plates 1 Glass trough 1 Set of 3 experiment leads, red 1 Set of 3 experiment leads, blue 1 Roll of experiment cord 1 Weight, 50 g 1 Tea candle
