An iron core in a transformer
A)guides magnetic field lines.
B)shields unwanted external electric or magnetic fields.
C)separates the primary and secondary regions.
D)reduces energy losses.

Question

Quizplus · Accepted Answer

An iron core in a transformer guides magnetic field lines, which helps in the transformation of electrical energy from one circuit to another. The core provides a path for the magnetic flux and increases the magnetic field strength, resulting in efficient energy transfer between the primary and secondary coils.
