Abstract

This project work was embarked on the construction and determination of the efficiency of 12 volts DC fan using two N3055 transistor, 1kΩ variable resistors, resistors, breadboard, veroboard, 12 volts DC battery and connectors at Science Laboratory Technological Department, Federal Polytechnic Offa, Nigeria. This is always required to minimize, control or totally eliminate the power fluctuations received at the load end or consumer end that usually lead to the reduction of DC fan lifespan. With the constructed DC fan, measurements were carried out using 25 volts adjustable DC regulated power supply system to feed in variable voltage and determine the output voltage and current to calculate its efficiencies at different resistance. The efficiencies determined at different resistance were compare and contrast. The threshold voltage was also determined at a particular resistance. Therefore, its uses require adequate knowledge of threshold and steady voltage to keeps it working at its highest efficiency that can make it more durable and increase its lifespan. Hence, the result of this project work recommends constant power source with steady input voltage above its threshold voltage to keeps the regulator working at its highest efficiency that can make it more durable and increase its lifespan.
