Question

Quizplus · Accepted Answer

Transformers operate on the principle of electromagnetic induction, in which changing magnetic fields cause a voltage to be induced in a nearby conductor. The two coils (or windings) of a transformer are arranged in close proximity with a magnetic core, allowing the magnetic field generated by one coil to induce a voltage in the other coil without any electrical connection between them. This allows for the transfer of electrical energy between two circuits without the need for direct contact or the use of moving parts. The choice of 60-Hz electric current or rectification are not relevant to the principle of operation of a transformer. The choice of step-up or step-down windings is a characteristic of transformer design, but not the underlying principle of operation.
