Diagram for question 232
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 would be closed to complete the circuit and allow current to flow to the motor. This is because the "F" contacts are associated with the forward rotation of the motor. The other answer choices are incorrect because: B) The normally closed "F" contacts would be open, not closed, when the motor is running forward. C) The normally open "R" contacts would not be closed, as they are associated with the reverse rotation of the motor. D) The normally closed "R" contacts would be open, not closed, when the motor is running forward.
