Often Confused With

anode vs cathode

The anode is where oxidation occurs (current enters), while the cathode is where reduction occurs (current leaves).

📝

Usage Notes

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).

⚠️

Common Mistakes

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

💡

Memory Tip

Remember 'An Ox': Anode = Oxidation. Both words start with vowels.

📖

Word Origin

From the Greek 'anodos', meaning 'way up', composed of 'ana' (up) and 'hodos' (way).
