Ribbon Polymer Capacitors. Basically capacitor is constructed of a dielectric polymer tape which is placed between two ribbons of aluminum (alluminium foil) as electrodes and rolled to obtain a desired electrode area. The roll is then inserted into the tube covered with aluminum or epoxy resin. Another construction is to use a layer of aluminum deposited (through evaporation) directly on ...

Through meticulously electrostatic interactions and the arrangement of atoms, will lead you on a deeper conceptual knowledge of the phenomenon of electric charge. Electric charge is a basic trait of nature that is affected by the structure of atoms. Benjamin Franklin gave the marking on the two types of electric charge as a positive charge and a negative charge. This ...

A. Rangkaian Seri Sebagaimana hambatan, rangkaian kapasitor dapat diklasifikasikanmenjadi dua jenis konfigurasi yakni, seri dan paralel, akan tetapi aturannya berbeda dan bahkan kebalikan dari aturan resistor. Kapasitor ekivalen (total/pengganti dari sebuah rangkaian seri empat dapat dihitung sebagai berikut: Gambar 3.17 Rangkaian Seri Kapasitor Karena besarnya arus dalam sebuah rangkaian seri sama dalam setiap kapasitor sesuai dengan hukum Kirchoff, maka dengan ...

A. Akurasi Suatu alat ukur dikatakan tepat jika mempunyai akurasi yang baik yaitu hasil ukur menunjukkan ketidakpastian yang kecil. Dapat juga dipahami sebagai seberapa dekat hasil ukur dengan nilai benarnya. Dalam hal ini sebelum sebuah alat ukur digunakan, harus dipastikan bahwa kondisi alat benarbenar dalam keadaan baik dan layak untuk digunakan, yaitu alat dalam keadaan terkalibrasi dengan baik. Kalibrasi yang ...
