Cathodic Protection Tester Practice Exam

Conventional current is defined as flowing in the direction of:

1. Anode to cathode through the metal

2. Catode to anode through the electrolyte

3. Electric field direction

4. Anode to cathode through the electrolyte

The correct answer is: Anode to cathode through the electrolyte

Conventional current refers to the flow of electric charge and is defined as flowing from the positive terminal to the negative terminal in a circuit. In the context of galvanic cells and electrolytic processes, the conventional flow of current is considered to occur from the anode (where oxidation takes place and positive charge is generated) to the cathode (where reduction occurs). When considering the electrolyte, which is the medium allowing the movement of ions, the direction of conventional current follows the path of positive charge movement. Hence, the acceptance of current flow from the anode to the cathode through the electrolyte accurately reflects the conventional current direction. Therefore, the statement associating current flow from the anode to the cathode through the electrolyte aligns with this fundamental understanding of how charge movement is defined in electrochemical processes.
