Frequentemente confundido com
The anode is where oxidation occurs (current enters), while the cathode is where reduction occurs (current leaves).
Notas de uso
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).
Erros comuns
Learners often mistakenly assume the anode is always positive; however, in a discharging battery, the anode is actually the negative terminal.
