  • Q1
    What is the purpose of the commutator in an electric motor?
    To generate electrical energy
    To change the direction of the current flowing in the armature
    To provide a mechanical connection between the rotor and stator
    To regulate the speed of the motor
  • Q2
    What is the function of the stator in an electric motor?
    To store electrical energy temporarily
    To convert electrical energy into mechanical energy
    To change the direction of the current flowing in the armature
    To create a magnetic field that interacts with the rotor
  • Q3
    What is the most common type of electric motor?
    Hybrid motor
    Stepper motor
    DC motor
    AC motor
  • Q4
    What determines the speed of an electric motor?
    The frequency of the power supply
    The number of poles in the stator
    The size of the motor
    The voltage of the power supply
  • Q5
    What is the purpose of the brushes in a DC motor?
    To provide a mechanical connection between the rotor and stator
    To regulate the speed of the motor
    To deliver electrical power to the armature
    To create a magnetic field in the stator
  • Q6
    What is the difference between a synchronous and an asynchronous motor?
    A synchronous motor operates only on DC, while an asynchronous motor operates on AC
    A synchronous motor operates at a constant speed, while an asynchronous motor has a speed that varies with the load
    A synchronous motor is more efficient than an asynchronous motor
    A synchronous motor does not have a rotor, while an asynchronous motor does
  • Q7
    Which type of energy does an electric motor convert into mechanical energy?
    Sound energy
    Electrical energy
    Chemical energy
    Light energy
  • Q8
    What is the rotating component of an electric generator called?
    Converter
    Rotor
    Transistor
    Stator
  • Q9
    What is the purpose of the commutator in an electric motor?
    To convert AC power to DC power
    To create the magnetic field in the stator
    To regulate the speed of the motor
    To reverse the direction of current flow in the armature
