Which outcome is expected when a sacrificial anode corrodes?

💡 Explanation

Cathodic protection weakens because the sacrificial anode undergoes preferential oxidation, therefore its *galvanic coupling* diminishes the protection it provides to the structure to be protected, rather than lowering anode reduction potential which is inherent.
