How Transformers Increase Voltage

Image
Transformers are crucial components in electrical power systems, primarily used to increase or decrease voltage levels to suit various applications. A step-up transformer is specifically designed to increase voltage, making it vital for efficient long-distance power transmission. The process by which transformers increase voltage is based on electromagnetic induction , a principle that enables energy transfer without physical connection between circuits. This article delves into the technical aspects of how transformers work to increase voltage, including detailed calculations, real-world applications, and energy considerations. Fundamental Working Principle The transformer operates on the principle of electromagnetic induction , discovered by Michael Faraday in 1831. When an alternating current (AC) flows through a coil, it generates a magnetic field that alternates at the same frequency as the current. This alternating magnetic field induces an electromotive force (EMF) or voltage i
