How does the transformer change the voltage?

Release time:2021-03-26 16:49:29 Popularity: Source:未知

      1831 Faraday's discovery of the electromagnetic induction scene from his experiments laid the groundwork for the creation of transformers. Later, according to the Faraday's law of induction and LENZ's law, we created the transformer. A transformer usually has two independent windings wound around the same closed iron core. The input power is called the primary winding, the output power is called the secondary winding. The magnetic field lines of communication current passing through the primary winding pass through the iron core and induce a voltage in the secondary winding. The difference in the number of primary and secondary windings enables the voltage to be changed from high to low.
