SPM Amali Physics: Cara Membaca & Menggunakan Ammeter (Analog) DC 0-1 A

 


🔌 Ammeter

👀 Cara Membaca | Reading Technique

✅ Baca skala pada paras mata yang sama dengan jarum penunjuk untuk mengelakkan parallax error.
Read the scale at eye level with the pointer to avoid parallax error.

✅ Pastikan skala yang dibaca sepadan dengan julat (range) yang dipilih.
Ensure the correct scale is used according to the selected range.

❌ Common Mistakes

❌ Menyambung terminal positif (+) dan negatif (−) secara terbalik.
Reversing the positive (+) and negative (−) terminals.

❌ Memilih julat terlalu kecil sehingga jarum melebihi had skala.
Selecting a range that is too low, causing the pointer to exceed the scale limit.

⚠️ Safety / Handling

⚠ Ammeter mesti disambung secara siri dalam litar.
⚠ An ammeter must always be connected in series in a circuit.

⚠ Jangan sambung terus merentasi bekalan kuasa.
⚠ Never connect an ammeter directly across a power supply.
