Soru

Zorluk: KolayElectricity and Magnetism

Electromagnetic principles are applied in many common electrical machines and tools. Match each device with its primary operational function.

  • Electric GeneratorConverts mechanical energy into electrical energy using electromagnetic induction
  • Electric MotorConverts electrical energy into mechanical rotational movement
  • TransformerIncreases or decreases alternating current (AC) voltage levels
  • ElectromagnetProduces a controllable magnetic field when an electric current passes through a coil

Cevap

Electric Generator matches with converting mechanical energy to electrical energy; Electric Motor matches with converting electrical energy to mechanical rotation; Transformer matches with adjusting alternating current voltage levels; Electromagnet matches with producing a controllable magnetic field from electric current.
Each electromagnetic device corresponds directly to its defined operational function: generators convert mechanical work into electricity, motors convert electricity into mechanical rotation, transformers step AC voltage up or down, and electromagnets create temporary magnetic fields via electric current.

Adım Adım Çözüm

1
Identify the energy transformation in an electric generator.
Mechanical energy is converted into electrical energy via induction.
Generators are driven by mechanical power to produce current.
2
Identify the energy transformation in an electric motor.
Electrical energy is converted into mechanical motion.
Motors consume electricity to produce physical torque and rotation.
3
Identify the primary role of a transformer in power distribution.
Voltage levels of alternating current are increased or decreased.
Transformers rely on changing magnetic flux between primary and secondary coils to adjust voltage.
4
Identify the mechanism of an electromagnet.
Current flowing through a coil creates a magnetic field.
Moving electric charges naturally produce magnetic fields around the coil.
