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
Fully covered resistance of 10kO
In normal room conditions it has a resistance of approximately 250O
