ABSRACT - [ Total Page(s): 1 ]ABSTRACTIn this project a resistance box has been constructed using locally available materials namely, 1/3 and plywood for the construction of the box, cupper wire, Ferro board, soldering iron, soldering lead, screw and resistors.The resistance obtainable from the box ranges from 2-11ï—. The box is fitted with terminal s to allow easy use in physics laboratory practical. At the end of the experiment, the values obtained are very close to those obtainable using imported box.

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.1 INTRODUCTIONIn many electrical measurements, standard variable resistances are required. These standard resistances come in various forms and shapes. The resistance box is one of them.These resistance boxes are imported and in most cases very expensive. Most schools can therefore not afford to buy enough for the use of there students. It is therefore important for technologists to be able to improvise using locally available materials.Also, during the course of designing and construction, student technologists are really exposed to more practical works in order to acquired a lot ...
