Plug Key: Function, Common Mistakes & SPM Physics Amali Tips

👀 Cara Membaca | Reading Technique

✅ Pastikan plug dimasukkan sepenuhnya sebelum mengambil bacaan.

✅ Ensure the plug is fully inserted before taking any reading.

✅ Semak bahawa litar lengkap dan meter menunjukkan bacaan yang stabil.

✅ Check that the circuit is complete and the meter shows a stable reading.

✅ Ambil bacaan hanya selepas semua sambungan dibuat dengan betul.

✅ Record readings only after all connections are properly secured.

❌ Common Mistakes

❌ Plug tidak dimasukkan sepenuhnya menyebabkan litar tidak lengkap.

❌ The plug is not fully inserted, resulting in an incomplete circuit.

❌ Menganggap litar masih lengkap selepas plug ditanggalkan.

❌ Assuming the circuit remains complete after the plug is removed.

❌ Sambungan wayar yang longgar pada terminal.

❌ Loose wire connections at the terminals.

⚠️ Safety / Handling

⚠️ Matikan bekalan kuasa sebelum memasukkan atau menanggalkan plug jika perlu mengubah sambungan litar.

⚠️ Switch off the power supply before inserting or removing the plug when modifying circuit connections.

⚠️ Pastikan terminal bersih dan bebas daripada kakisan.

⚠️ Ensure the terminals are clean and free from corrosion.

⚠️ Elakkan menarik wayar secara kasar semasa mengendalikan plug key.

⚠️ Avoid pulling the wires forcefully when handling the plug key.

🎯 SPM Exam Tip

📌 Plug key biasanya digunakan untuk mengawal aliran arus semasa eksperimen dijalankan.

📌 A plug key is commonly used to control the flow of current during an experiment.

📌 Apabila plug dimasukkan, litar lengkap dan arus mengalir.

📌 When the plug is inserted, the circuit is complete and current flows.

📌 Apabila plug ditanggalkan, litar terbuka dan arus terhenti.

📌 When the plug is removed, the circuit becomes open and current stops flowing.
