使い方のコツ

The term is used exclusively in the fields of chemistry, physics, and electronics. The charge of an anode (positive or negative) depends on whether the device is consuming power (like an electrolytic cell) or providing power (like a discharging battery).

⚠️

よくある間違い

Learners often mistakenly assume the anode is always positive; however, in a discharging battery, the anode is actually the negative terminal.
