In an impressed current system, the rectifier positive terminal is connected to:

• A. Anodes
• B. The structure
• C. The negative terminal
• D. The soil

Answer: (B)

In an impressed current system, the rectifier positive terminal is connected to the structure to be protected. This setup is essential for the operation of cathodic protection systems, where the rectifier generates a direct current that is applied to the structure to mitigate corrosion. By connecting the positive terminal to the structure, a flow of electrons is directed towards the anodes installed near the structure, allowing for effective corrosion protection. The structure serves as the cathode in the system, thus making it crucial for maintaining the integrity and lifespan of materials that might otherwise corrode in the presence of moisture and other corrosive elements. Properly connecting the rectifier in this manner ensures that the system can deliver the necessary protective current effectively.
