Principles of Direct-current Electrical Engineering

Clifford Copland Paterson was born on 17 October 1879 at Stoke Newington, and was the son of Frederick Paterson, a tanner and leather merchant. In 1892, after attending a private school near his home, he entered Mill Hill, then under the headmastership of McClure, later Sir John; he went on the modern side and specialized in the study of engineering and physics. Though he reached the sixth form and gained prizes for French and German, his school career seems, on the whole, to have been undistinguished and to have given little promise of the outstanding ability that was to develop later. After leaving Mill Hill in 1896, Paterson embarked on a comprehensive training, both theoretical and practical, in general and electrical engineering. He first spent a year at Finsbury Technical College and then served a general engineering apprenticeship with Messrs George Wailes and Company of London, and subsequently with Messrs Mirrlees, Watson and Company of Glasgow. In 1901 he entered Faraday House, under Alexander Russell, as a special studentassistant in the Testing Department. Shortly after, he published, jointly with Russell, his first paper, which dealt with sparking in switches. The general adoption, about this time, of higher supply voltages made the rating of switches for use in direct current lighting circuits a matter of pressing importance. Widely different ratings were being given by different makers for switches of substantially the same size and length of break. The primary object of the work was therefore to determine detailed relations between current, voltage and the resulting spark length, so as to enable manufacturers to predict the behaviour of their switches under various conditions.

Electrical Engineering Education

The development of technology with the presence of gadgets and the internet also affects the lifestyle of everyonr, youtube as social media that can be used as as learning resource and task collection is able to provide additional information for the learning process and increase the ability of students to understand ability in the learning process of partical subject. In this researce using quantitative approach with descriptive correlational method. This research aims to determine the correlation application youtube in collection of tasks with learning outcomes direct current machine subject of Electrical Engineering Education Students in 110th semester. Youtube is currently the most important popular situs and almost various groups use youtube. The population in this research is the students in Electrical Engineering Education, Faculty of Engineering, State University of Jakarta who take direct current machine subject, while the sample in this study were 65 students. The results showed that hypothesis test with significant level 5% was obtained rcount = 0,151 and rtable = 0,244, because of the rcount < rtable it can be concluded that there was no significant correlation between the use of youtube with learning outcomes of Electrical Engineering Education students, State University of Jakarta who take direct current machine subject in 110th semester because in the direct current machine subject youtube s used as a media for task collection. Abstrak Berkembangnya teknologi dengan adanya gadget dan internet juga mempengaruhi gaya hidup setiap orang, youtube sebagai media sosial yang dapat digunakan sebagai media pembelajaran dan pengumpulan tugas mampu memberikan informasi tambahan untuk proses pembelajaran dan menambah kemampuan pemahaman mahasiswa dalam proses belajar mata kuliah praktik. Penelitian ini bertujuan untuk mengetahui hubungan penggunaan youtube dalam pengumpulan tugas dengan hasil belajar mata kuliah mesin arus searah mahasiswa Pendidikan Teknik Elektro Universitas Negeri Jakarta pada semester 110. Youtube saat ini menjadi situs yang paling populer dan hampir berbagai kalangan menggunakan youtube. Pada penelitian ini menggunakan pendekatan kuantitatif dengan metode deskriptif korelatif. Populasi dalam penelitian ini adalah mahasiswa program studi Pendidikan Teknik Elektro yang mengambil mata kuliah mesin arus searah, sedangkan sampel dalam penelitian ini berjumlah 65 orang mahasiswa Pendidikan Teknik Elektro semester 110 yang mengambil mata kuliah mesin arus searah. Teknik analisis yang digunakan adalah uji prasyarat analisis menggunakan uji normalitas dan uji linieritas. Hasil penelitian menunjukkan bahwa uji hipotesis dengan taraf signifikansi 5% diperoleh rhitung = 0,151 dan nilai rtabel = 0,244, karena nilai rhitung < rtabel maka dapat disimpulkan bahwa tidak terdapat hubungan yang signifikan antara penggunaan youtube dengan hasil belajar mahasiswa Pendidikan Teknik Elektro Universitas Negeri Jakarta yang mengambil mata kuliah mesin arus searah pada semester 110 karena dalam mata kuliah mesin arus searah youtube baru digunakan sebagai media pengumpulan tugas.
