Zorluk: KolayInductors and Transformers

Electromagnetic components are essential for controlling current and voltage levels in alternating current circuits. Which characteristic or operational principle correctly corresponds to each listed component or term?

  • Step-up transformerA device with more secondary turns than primary turns that increases alternating voltage
  • InductorA device that opposes rapid changes in electric current by storing energy in a magnetic field
  • HenryThe standard unit of measurement for electrical inductance
  • Mutual inductionThe process by which a changing current in one coil induces an electromotive force in an adjacent coil

Cevap

Step-up transformer matches a device with more secondary turns than primary turns that increases alternating voltage; Inductor matches a device that opposes rapid changes in electric current by storing energy in a magnetic field; Henry matches the standard unit of measurement for electrical inductance; Mutual induction matches the process by which a changing current in one coil induces an electromotive force in an adjacent coil.
Each item is matched to its exact operational role and definition: the step-up transformer increases AC voltage via a greater secondary turn count; the inductor resists current changes through magnetic storage; the henry serves as the unit of inductance; and mutual induction represents the principle of transferring energy across coupled coils.

Adım Adım Çözüm

1
Identify the function of a step-up transformer.
A step-up transformer increases alternating voltage because its secondary winding has more turns than its primary winding (Ns>NpN_s > N_p).
According to the transformer turns ratio formula, VsVp=NsNp\frac{V_s}{V_p} = \frac{N_s}{N_p}, higher secondary turns produce higher secondary voltage.
2
Identify the operating behavior of an inductor.
An inductor resists sudden current fluctuations by temporarily storing electrical energy in a concentrated magnetic field.
Lenz's law states that the induced back-EMF always acts to oppose the original change in current.
3
Identify the standard unit for inductance.
The henry (H\text{H}) is the recognized unit of electrical inductance.
One henry of inductance induces an electromotive force of one volt when the current changes at a rate of one ampere per second.
4
Identify the definition of mutual induction.
Mutual induction is the magnetic coupling effect where current variations in a primary winding induce a voltage across a separate secondary winding.
This electromagnetic linkage allows electrical energy to transfer between isolated circuits without direct conductive contact.
