Suis terbuka memutuskan litar. Periksa dan tutup suis sebelum menukar komponen lain.
Langkah 1
Suis mungkin masih terbuka
Suis terbuka memutuskan litar. Periksa dan tutup suis sebelum menukar komponen lain.
suis terbuka → laluan terputus
suis terbuka = 开关断开(没有按下) 灯不亮时,先检查开关。科学上 suis terbuka 指开关断开、电路不通;suis tertutup 才是接通。开关断开会让电的路断掉,所以要先把开关关上,再考虑换别的零件。 例子:电视开不了,先看插座开关有没有按下,再说电视坏了。 注意:不要一开始就换灯泡或电池,最简单的原因要最先检查。
suis terbuka = open switch When the bulb does not light, check the switch first. An open switch breaks the path, so close it before changing any other part. Example: If the TV will not turn on, first check that the wall socket switch is pressed down before saying the TV is broken. Watch out: Do not replace the bulb or cell straight away; check the simplest cause first.
Langkah 2
Sel kering mungkin kekurangan tenaga
Sel kering lama mungkin tidak membekalkan tenaga yang mencukupi. Gantikan dengan sel kering yang diketahui masih baik untuk menguji ramalan.
sel lama → uji dengan sel baik
sel kering kekurangan tenaga = 干电池没电 旧的干电池可能电力不够。换上一颗确定是好的电池,就能测试你的猜测对不对。 例子:遥控器不灵,换上新电池后又能用了,说明是旧电池没电。 注意:电池看起来新,不一定有电;要用测试来证明,不能只用眼睛看。
sel kering kekurangan tenaga = a weak dry cell An old dry cell may not supply enough energy. Swap in a cell that you know is good to test your prediction. Example: A remote control stops working, then works again with new batteries, so the old ones were flat. Watch out: A cell that looks new may still be flat; prove it with a test instead of judging by its look.
Langkah 3
Mentol atau sambungan mungkin rosak
Mentol rosak atau wayar longgar juga menyebabkan litar gagal. Tukar atau kemaskan satu perkara sahaja pada setiap ujian.
ubah satu perkara → uji → catat
mentol atau sambungan rosak = 灯泡或接线坏了 灯泡坏了或电线松了,电路也会失灵。每次测试只换或只修一样东西,然后记录结果。 例子:先拧紧电线,灯不亮;再换灯泡,灯亮了,就知道是灯泡坏。 注意:一次改两样,就算灯亮了,也不知道是哪一样修好的。
mentol atau sambungan rosak = faulty bulb or connection A broken bulb or loose wire can also make the circuit fail. In each test, change or fix only one thing, then record the result. Example: Tighten the wires and the bulb stays dark; replace the bulb and it lights, so the bulb was faulty. Watch out: If you change two things at once, you cannot tell which one fixed the circuit.

Mentol tidak menyala dan suis kelihatan terangkat. Apakah yang patut diperiksa dahulu?
punca paling mudah = 最容易检查的原因 题目问灯不亮时,哪个原因最容易先检查。想一想:哪个原因看一眼、动一下手指就能改?也要问每个选项是否真的会让电路断掉。 例子:门打不开,先看是不是没转门把,再怀疑锁坏了。 注意:paling mudah 要同时符合两点:容易检查,而且真的会影响电路。
punca paling mudah = the easiest cause The question asks which cause to check first when the bulb will not light. Think about which cause can be seen at a glance and fixed with one finger, and whether each choice could really break a circuit. Example: If a door will not open, check the handle was turned before blaming the lock. Watch out: Paling mudah needs two things: easy to check, and truly able to affect the circuit.

Bagaimanakah menguji sel kering lama?
menguji sel kering lama = 测试旧电池 题目问怎样知道旧电池还有没有电。想一想公平的科学测试:用一样确定是好的东西来比较,结果才可信,而且做法要安全。 例子:怀疑温度计坏了,就和另一支好的温度计量同一杯水来比较。 注意:好的测试要给出清楚的结果,做完后要知道电池是好是坏。
menguji sel kering lama = testing an old dry cell The question asks how to find out whether an old cell still works. Think of a fair scientific test: compare with something you trust so the result is reliable, and make sure the method is safe. Example: If you doubt a thermometer, measure the same cup of water with another thermometer you trust. Watch out: A good test must give a clear result that tells you whether the cell is good or flat.
