cực dương
Definition
- Noun:
- Positive electrode, anode: In electricity and electronics, "cực dương" refers to the electrode with a positive electrical charge. It is the terminal toward which electrons (negative charge) flow in an external circuit or from which conventional current (positive charge) flows out. It is the opposite of the cathode (cực âm).

Advanced Usage
"Điện cực dương": This is a more formal or technical term for "positive electrode," often used in scientific contexts.
- Điện cực dương của tế bào nhiên liệu thường được làm từ platin. (The positive electrode of a fuel cell is often made of platinum.)
In battery terminology: "Cực dương" is marked with a plus sign (+). It is the terminal from which conventional current is considered to exit a source, such as a battery or generator.
- Nhớ lắp pin đúng chiều: cực dương (+) hướng lên trên. (Remember to insert the battery correctly: the positive terminal (+) facing upward.)
