trent builds a model electric motor. when he connects a battery to the motor, the motor spins through a half rotation and stops. which is the most likely solution to the problem? replacing the battery, because it is not providing current installing new brushes, because they are not making a good connection checking the commutator, because the current is not reversing adding more wire coils in the armature, because the electromagnet is too weak
Answer
Brief Explanation:
In an electric - motor, the commutator's role is to reverse the current direction in the armature coil at regular intervals to keep the motor rotating. If the motor spins through a half - rotation and stops, it is likely that the current is not reversing, which is a commutator issue.
Answer:
checking the commutator, because the current is not reversing
