Simple Circuit Modules.

These modules may be used to construct simple circuits of the type normally implemented on, for example, a Worcester Circuit Board. They are intended to introduce younger pupils (ages 11-13) to some of the more familiar applications of devices and circuits, the main emphasis being on simple electrical circuit work.

The modules are 60 x 60mm and have 4mm plug connections.

• This is a ORP13, 4mm light dependent resistor.
• In normal conditions resistance is 220 Ohm approximately.
• Fully covered resistance is 40 K ohm approximately.
