Transformer Transformer Principle
Transformers rely on two coils to transform. Principle is in the case of loss without loss according to the input power = output power, that is, P1 = U1 * I1 = U2 * I2 = P2 to change the pressure, specifically in high school physics textbooks, I now basically forget
The transformer is a high-pressure water (electricity); outlet is a low-pressure water (electricity)! Transform pressure is buck! Reverse can also! Pool to increase the pump Change the high pressure water! Transformers to replace the iron! Like low-pressure water sealed water tank at the bottom of the high-pressure water! Understand it! Haha! I as a lecturer?
Summary of words: Electrosagnetism. Magnetic electricity.
Its basic principle is: a coil and the secondary coil around the same core, when a coil power, the alternating magnetic flux in the core, (magnetism) the alternating magnetic flux through the secondary Coil, according to the law of electromagnetic induction, will produce alternating electric potential in the secondary coil, (magnetic power) due to a secondary side of the coil turns, therefore, the secondary side of the voltage will not wait.
