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

 

👀 Cara Membaca | Reading Technique

✅ Pastikan litar hanya lengkap apabila butang ditekan.

✅ Ensure the circuit is completed only when the button is pressed.

✅ Perhatikan perubahan pada mentol, ammeter atau galvanometer semasa kekunci ditekan.

✅ Observe changes in the bulb, ammeter or galvanometer when the key is pressed.

✅ Lepaskan kekunci selepas bacaan diperoleh jika eksperimen memerlukan arus mengalir seketika sahaja.

✅ Release the key after obtaining the reading when temporary current flow is required.

❌ Common Mistakes

❌ Menekan kekunci terlalu lama sehingga komponen menjadi panas.

❌ Holding the key down for too long, causing components to heat up.

❌ Menganggap tapping key berfungsi seperti suis biasa yang kekal ON.

❌ Assuming a tapping key works like a normal switch that stays ON.

❌ Tidak melepaskan kekunci selepas bacaan diperoleh.

❌ Failing to release the key after the required reading is taken.

⚠️ Safety / Handling

⚠️ Tekan kekunci hanya apabila bacaan hendak diambil.

⚠️ Press the key only when a reading is required.

⚠️ Elakkan menekan terlalu lama bagi mengurangkan pemanasan wayar dan komponen.

⚠️ Avoid prolonged pressing to reduce heating of wires and components.

⚠️ Pastikan terminal disambung dengan kemas sebelum eksperimen dijalankan.

⚠️ Ensure all terminals are securely connected before starting the experiment.

🎯 SPM Exam Tip

📌 Tapping key biasanya digunakan dalam eksperimen yang melibatkan galvanometer, medan magnet dan induksi elektromagnet.

📌 A tapping key is commonly used in experiments involving galvanometers, magnetic fields and electromagnetic induction.

📌 Tujuannya ialah membenarkan arus mengalir untuk masa yang sangat singkat.

📌 Its purpose is to allow current to flow for a very short duration.

📌 Dalam jawapan SPM, nyatakan bahawa tapping key digunakan untuk melengkapkan litar secara sementara.

📌 In SPM answers, state that a tapping key is used to complete a circuit momentarily.
