  The Basics of Electrical Transformers----- What are Electrical Transformers? Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about an increase in the voltage and vice versa. Transformers help improve safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances. The Construction of an Electrical Transformer The three important components of an electrical transformer are a magnetic core, primary winding, and secondary winding. The primary winding is the part that is connected to an electri...
