    Berapakah nilai kapasitor berikut ini?

    • 0,068 uF

    • 600 uF

    • 0,068 nF

    • 600 nF

    Correct Answer
    A. 0,068 uF
    Explanation
    The correct answer is 0,068 uF. The given values are in different units of capacitance: microfarads (uF) and nanofarads (nF). To compare them, we need to convert them to the same unit. 1 uF is equal to 1000 nF. Therefore, 0,068 uF is equivalent to 68 nF. Since the other options are 600 uF and 600 nF, they do not match the given value.

    Kapasitor yang bertuliskan 2n2 nilainya ….

    • 22000 pF

    • 2200 pF

    • 220 pF

    • 2,2 pF

    Correct Answer
    A. 2200 pF
    Explanation
    The correct answer is 2200 pF. The question is asking for the value of a capacitor that is labeled as 2n2. The "n" in this context represents nano, which is a metric prefix indicating one billionth of a unit. Therefore, 2n2 translates to 2.2 nano farads (nF). To convert nF to pF (pico farads), we multiply by 1000. Thus, 2.2 nF is equal to 2200 pF.

    Satuan resistor adalah ohm karena ohm merupakan satuan yang digunakan untuk mengukur resistansi atau hambatan dalam rangkaian listrik. Resistansi adalah sifat resistor yang menghambat aliran arus listrik. Satuan ohm dinamai sebagai penghormatan kepada Georg Simon Ohm, seorang fisikawan Jerman yang menemukan hukum Ohm yang menjelaskan hubungan antara arus, tegangan, dan resistansi dalam sebuah rangkaian listrik.

    Dioda zenner berfungsi sebagai ….

    • Input tegangan

    • Penurun tegangan

    • Pembatas tegangan

    • Penyearahkan tegangan

    Correct Answer
    A. Pembatas tegangan
    Explanation
    Dioda zenner berfungsi sebagai pembatas tegangan. Dioda ini dirancang untuk bekerja dalam keadaan terbalik, yang memungkinkan aliran arus hanya dalam satu arah. Ketika tegangan melebihi tegangan zenner yang ditentukan, dioda zenner akan "membuka" dan mengalirkan arus melalui sirkuit, sehingga membatasi tegangan pada nilai yang ditentukan. Dengan demikian, dioda zenner berfungsi untuk melindungi sirkuit dari lonjakan tegangan yang berlebihan.

    Berikut ini pembagian IC berdasar jumlah komponennya, kecuali ….

    • VLSI

    • SSI

    • MSI

    • LPI

    Correct Answer
    A. LPI
    Explanation
    The given options VLSI, SSI, MSI, and LPI represent different categories of integrated circuits based on the number of components they contain. VLSI stands for Very Large Scale Integration and refers to circuits that contain a large number of components. SSI stands for Small Scale Integration and represents circuits with a small number of components. MSI stands for Medium Scale Integration and refers to circuits with a moderate number of components. LPI, however, is not a recognized category and does not represent a specific number of components. Therefore, LPI is the correct answer as it does not fit into the pattern of the other options.

    Jenis speaker yang mereproduksi sinyal audio frekuensi tinggi adalah ….

    • Tweeter

    • Woofer

    • Full range

    • Sub woofer

    Correct Answer
    A. Tweeter
    Explanation
    A tweeter is a type of speaker that is specifically designed to reproduce high-frequency audio signals. It is responsible for producing clear and detailed sound in the higher frequency range. Unlike woofers or subwoofers, which are designed to handle lower frequency sounds, a tweeter focuses on reproducing the higher end of the audio spectrum. Therefore, a tweeter is the correct answer for this question.

    Kapasitor 30 nF dan 60 nF dirangkai seri, maka   nilai totalnya adalah ….

    • 20 nF

    • 30 nF

    • 60 nF

    • 90 nF

    Correct Answer
    A. 20 nF
    Explanation
    When capacitors are connected in series, the total capacitance is calculated by using the formula: 1/Ctotal = 1/C1 + 1/C2 + 1/C3 + ... In this case, the given capacitors are 30 nF and 60 nF. Plugging in the values into the formula, we get: 1/Ctotal = 1/30 + 1/60. Simplifying the equation, we find that 1/Ctotal = 2/60 + 1/60 = 3/60. Inverting both sides of the equation, we get Ctotal = 60/3 = 20 nF. Therefore, the total capacitance is 20 nF.

    Huruf “K” pada kode nilai kapasitor menunjukkan toleransi nilai kapasitor sebesar ….

    • 1 %

    • 5 %

    • 10 %

    • 20 %

    Correct Answer
    A. 10 %
    Explanation
    The letter "K" in the capacitor value code indicates the tolerance of the capacitor value, which is 10%.
