Thesis (Bachelor of Secondary Education major in Physical Sciences) -- University of Rizal System-Morong.

EXECUTIVE SUMMARY: This study aimed to develop an Electricity Generator as Laboratory Apparatus. It was conducted at the University of Rizal System Morong Campus during the academic year 2014-2015. The study made use of the developmental and descriptive research design because it aimed to descriptive how the output was developed and to determine the relationship of the revolution per minute to the value of the induced electromotive force (emf). The researchers conducted five trials of two different sizes of coils, revolution per minute and coil connections: series and parallel, to determine the relationship of the revolution per minute, sizes of coils and coil connections to the amount of induced electromotive force produced by the laboratory apparatus. There were set of activities made as supplementary material of the Output. This study utilized information from different sources related to this study. The mean was used for data analysis to establish the average values for different electrical quantities such as voltage without load, voltage with load, current with load and power. Qualitative discussion was used to discuss the construction of the output. After conducting the study, the researchers conclude that the Electricity Generator as Laboratory Apparatus produced as greater voltage and current on Coils Connected in Series than in Parallel and the greater revolution per minute (rpm) induced greater amount of voltage and current which supports the Law of Electromagnetic Induction in Physics by Michael Faraday. This Laboratory Apparatus can be used in teaching Electricity and Magnetism subject specifically electromagnetic induction. The summary of findings with regards to coils connected in series, the values measured and computed were greater under 170 rpm than 95 rpm. The total voltage of with or without load measured in combined coils is almost equal to the sum of the voltage in coils 29 and 32. The current measured in combined coils is almost the same in each voltage measured in individual coil. The power is dependent on the measured current and voltage with load since the power was computed through the cross product of current and voltage and is directly proportional. With regards to coils connected in parallel, the values measured and computed were greater were greater under 170 rpm than 95 rpm. The total voltage of with or without load measured in combined coils is equal to the total voltages in coils 29 and 32. The current measured in combined coils is the total in each voltages measured in individual coil. The power is dependent on the measured current and voltage with load since the power was computed through the cross product of current and voltage and they are directly proportional to each other. The Electricity Generator produced greater voltage and current on Coils Connected in Series in Parallel.
