sel kering = dry cell A dry cell is the source of electrical energy for a simple circuit. Its positive (+) and negative (−) terminals must match the marks on the holder. Example: When you change batteries in a TV remote, follow the + and − pictures inside the case. Watch out: A dry cell supplies energy but gives no light itself; do not mix it up with the bulb.
Langkah 2
Mentol dan suis mempunyai tugas berbeza
Mentol mengeluarkan cahaya apabila litar lengkap. Suis menyambungkan atau memutuskan laluan arus elektrik.
mentol: cahaya | suis: buka atau tutup litar
mentol dan suis = 灯泡和开关 电路完整时，灯泡会发光。开关的工作是接通或切断电流走的路。 例子：按下房间墙上的开关，天花板的灯就亮；再按一次，灯就熄。 注意：开关本身不产生电，它只是控制电路通还是断。
mentol dan suis = bulb and switch The bulb gives out light when the circuit is complete. The switch connects or breaks the path of the electric current. Example: Press the wall switch in your room and the ceiling light comes on; press it again and it goes off. Watch out: A switch makes no electricity; it only decides whether the path is joined or broken.
Langkah 3
Wayar menyambungkan semua komponen
Wayar penyambung menghubungkan sel kering, mentol dan suis menjadi satu laluan lengkap. Hujung wayar perlu dipasang kemas.
wayar penyambung = connecting wire Connecting wires join the dry cell, bulb and switch into one complete path. Each end of a wire must be fixed firmly. Example: A phone charging cable joins the charger to the phone so electricity can flow. Watch out: A loose wire end may look connected, but electricity cannot pass through the gap.

Komponen manakah membekalkan tenaga elektrik?
membekalkan tenaga elektrik = 供应电能 题目问电路里哪个零件提供电能。回想每个零件的工作：哪个发光、哪个控制通断、哪个才是能量的来源？ 例子：太阳能板把阳光变成电，为路灯提供电能。 注意：会亮的零件，不一定就是提供能量的那一个。
membekalkan tenaga elektrik = supplying electrical energy The question asks which part provides the energy in a circuit. Recall each part's job: which one shines, which one controls the path, and which one is the energy source? Example: A solar panel turns sunlight into electricity and supplies energy to a street lamp. Watch out: The part that lights up is not necessarily the part that supplies the energy.

Apakah fungsi wayar penyambung?
fungsi wayar = 电线的作用 题目问连接电线有什么用。想一想：电线本身会不会发光？会不会装东西？没有它，各个零件之间会怎样？ 例子：电线外层的塑料皮，能保护我们不触电。 注意：每个零件只有一个主要工作，要分清选项说的是哪一个零件的工作。
fungsi wayar = function of the wire The question asks what a connecting wire does. Think: does a wire shine, does it store things, and what would happen between the parts without it? Example: The plastic coating on a wire protects us from electric shocks. Watch out: Each part has one main job, so check which part each choice is really describing.
