[0002] The transformer mainly works based on the principle of electromagnetic induction; it is composed of a primary coil, a secondary coil and a core (or a magnetic core); when the primary coil is connected to an AC power supply, alternating current will be generated in the coil, thereby generating alternating magnetic flux in the core; this alternating magnetic flux will simultaneously pass through the primary coil and the secondary coil, and according to the law of electromagnetic induction, an induced electromotive force will be generated in the secondary coil. The domestic transformer is a kind of transformer, which is used for voltage conversion or adaptation equipment in the home environment, and plays a crucial role in the process of household power transmission and distribution.
