The lamp board is a device for showing the effect of different kinds of series, parallel, and series-parallel circuit hook-ups via the brightness of light bulbs acting as resistances. The board’s convenient strap-connectors allow a combination of two to five lights in series-parallel mixes. By using the lamp board alone, the user can optically see how electrical energy is being distributed due to a particular hookup. By using electrical meters, it is possible to make quantitative measurements of the distribution of energy, but such measurements are only recommended for advanced students. Included with this useful kit are seven light bulbs (five for the board, two extras), and very comprehensive instructions for using the board effectively either in experiments or in a classroom environment. The lamp board is an excellent resource for teachers and students.
