Diagram for USCG Electrical QMED: Referring to figure "B" of the illustrated control circuit schematic diagram,...

AThe normally open (NO) "F" contacts are closed.

BThe normally closed (NC) "F" contacts are closed.

CThe normally closed (NC) "R" contacts are open.

DThe normally open (NO) "R" contacts are closed.

AI Explanation

The correct answer is A) The normally open (NO) "F" contacts are closed. When the motor is running in the forward direction, the normally open "F" contacts will be closed, allowing current to flow through the forward circuit. This is the expected behavior for a motor control circuit, where the "F" (forward) contacts are energized to run the motor in the forward direction. The other answer choices are incorrect because: B) The normally closed (NC) "F" contacts would be open, not closed, when running in the forward direction. C) The normally closed (NC) "R" contacts would be closed, not open, when running in the forward direction. D) The normally open (NO) "R" contacts would be open, not closed, when running in the forward direction.
