NCCER Electrical Module 2 Level 2 exam 2023 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 Types of DC motors - correct answer -Shunt Series Compound
