Step 1: Explain the principle of operation of an AC transformer. An AC transformer operates on the principle of electromagnetic induction, specifically mutual induction. It consists of two coils, a primary coil and a secondary coil, wound around a common soft iron core. When an alternating current (AC) flows through the primary coil, it produces a continuously changing magnetic flux in the core. This changing magnetic flux links with the secondary coil, inducing an alternating electromotive force (EMF) or voltage across its terminals, according to Faraday's law of electromagnetic induction. The ratio of the induced voltage in the secondary coil to the voltage applied to the primary coil is proportional to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil. 3 done, 2 left today.
