    Correct Answer
    C. 2), 3), 5)
    Explanation
    The correct answer is 2), 3), 5). This is because statement 2) mentions "Memiliki bentuk tegangan" which translates to "Has the form of voltage" and statement 3) mentions "Memiliki lambang :" which translates to "Has the symbol :" and statement 5) gives examples of sources of alternating current (AC) such as PLN electricity, AC generator, and bicycle dynamo. These statements indicate that the source mentioned has an alternating voltage, which is represented by a symbol, and is exemplified by AC sources.

      1) dan 2)

    Correct Answer
    D. 1) dan 2)
    Explanation
    The correct answer is 1) dan 2). This is because in a Voltaic cell, two different metals are used as electrodes, with one metal being the anode and the other being the cathode. In this case, Cu (tembaga) and Zn (seng) are both metals and can be used as electrodes in a Voltaic cell.

    • D.

      4)

    Correct Answer
    C. 3)
    Explanation
    The correct answer is 3) NH4Cl. The explanation for this is that NH4Cl is an electrolyte because it dissociates into NH4+ and Cl- ions when dissolved in water. In a dry cell battery, the electrolyte is typically a paste or gel that contains NH4Cl, which allows for the flow of ions and the generation of electricity. Therefore, NH4Cl is the most suitable electrolyte for use in a dry cell battery.

    • A.

      Energi kimia --> energi cahaya --> energi listrik

    • B.

      Energi listrik --> energi kimia --> energi cahaya

    • C.

      Energi kimia --> energi listrik --> energi cahaya

    • D.

      Energi listrik --> energi cahaya --> energi kimia

    Correct Answer
    C. Energi kimia --> energi listrik --> energi cahaya
    Explanation
    When a battery is used to power a flashlight, the energy transformation that occurs is from chemical energy stored in the battery to electrical energy, which is then converted to light energy. This is because the chemical reactions happening inside the battery produce an electric current, which flows through the circuit of the flashlight and powers the light bulb, converting the electrical energy into light energy.

    • D.

      Keping-keping seng dan tembaga yang terendam mudah rusak

    Correct Answer
    C. Timbul gelembung gas hidrogen yang menempel pada anoda
    Explanation
    The correct answer is "timbul gelembung gas hidrogen yang menempel pada anoda." When a voltaic cell is in operation, the anode undergoes oxidation, releasing electrons and producing hydrogen ions. These hydrogen ions then react with the electrons at the cathode to form hydrogen gas. Over time, these hydrogen bubbles can build up on the surface of the anode, reducing the surface area available for the reaction to occur. This can hinder the flow of current and decrease the efficiency of the voltaic cell.

    • D.

      Lempeng tembaga

    Correct Answer
    A. Lempeng timbal
    Explanation
    The correct answer is "lempeng timbal" because in an accumulator, the negative electrode is typically made of lead (timbal). This electrode is responsible for storing and releasing electrons during the charging and discharging process of the accumulator.
