NCCER Electrical Module 2 Level
2 exam 2025 with 100% correct answers
, How DC motors operate? - correct answer -Magnetic lines of force are continuous and always form closed
loops; Magnetic lines of force do not cross.
Armature: (Definition) - correct answer -The rotating windings of a DC motor.
The is a movable electromagnet located between the poles of another fixed permanent (field) magnet
as shown. - correct answer -Armature
A twisting force called must be developed. is produced by mounting a loop in a fixed
magnetic field and as long as the fields of the magnet and armature interact. - correct answer -Torque
Commentator: (Definition) - correct answer -A device used on electric motors or generators to maintain a
unidirectional current.
In the neutral plane, no is produced and the rotation of the armature should stop - correct answer
-Torque
A is produced by the fields poles, and a loop of wire in the armature turns and cuts this magnetic field. -
correct answer -Magnetic field
CEMF - correct answer -Counter electromotive force (CEMF)
Horsepower: (Definition) - correct answer -The rated output capacity of the motor. It is based on breakdown
torque, which is the maximum torque a motor will develop without an abrupt drop in speed.
Horsepower: (Equation) - correct answer -Hp= Watts/746
