Question 428Electricity & Electronics - QMED

The correct answer is D) straps connect the rudder with the hull and the propeller shaft is grounded through a slip ring/brush arrangement. This is correct because grounding the propeller shaft and connecting the rudder to the hull are important features in an impressed current cathodic protection system. The grounded shaft prevents stray current from flowing through the shaft, which could lead to corrosion. Connecting the rudder to the hull ensures that it is also protected from corrosion. The other options are incorrect because they do not directly relate to the features of an impressed current cathodic protection system. Aligning the hull's magnetic fields, adding temperature sensors, and coating machinery with zinc chromate are not typical components of this type of corrosion protection system.
