Transformers use ac to satisfy the required
A)transfer of energy from coil to coil.
B)voltage for transformation.
C)change in magnetic field for operation.
D)change in input current.
E)magnetic field intensities.

Question

Quizplus · Accepted Answer

Transformers operate on the principle of electromagnetic induction, which requires a changing magnetic field to induce a voltage in the secondary coil. AC (alternating current) naturally changes direction and magnitude, creating a constantly changing magnetic field necessary for transformer operation.
