Electrolysis Practice Exam

Electrodes are functionally similar to which of the following components?

1. Resistors

2. Capacitors

3. Conductors

4. Inductors

The correct answer is: Conductors

The correct choice is conductors, as electrodes serve as the surfaces through which electric current enters or exits an electrolyte in electrolysis. Just like conductors, which allow the flow of electrical current, electrodes facilitate the transfer of electrons during the electrolysis process. They play a critical role in carrying out the electrochemical reactions essential to electrolysis. Resistors, capacitors, and inductors have different functions in electrical circuits. Resistors limit current flow, capacitors store electrical energy, and inductors store energy in a magnetic field. While electrodes can conduct electricity, their primary function in electrolysis is to facilitate reactions by enabling the movement of ions and the transfer of electrons, which distinctly aligns them with the role of conductors.
