About :

Hello everyone, in this video we are showing how to connect a transformer with center tap. The secondary of this transformer has three wires, two at the ends and one in the middle. In this secondary we actually have two coils and the middle wire joins these two coils adding two voltages. For example: 12V at one end and 12V at the other end as the middle wire joins the two coils 12V plus 12V = 24V. NOTE: IN THE DRAWING SHOWN IN THIS PROJECT I AM USING 6 VOLTS AND NOT 12 VOLTS OK. To add 6 Volts plus 6 Volts the connection would be different from the one shown in the drawing. IN THE DRAWING WHERE I PUT 12 VOLTS IS WRONG IT IS NOT 12 VOLTS BUT 6 VOLTS. A transformer is a device designed to modify the levels of voltage and electrical current, maintaining a practically constant electrical power, from one circuit to another, also modifying the values ​​of the electrical impedances of an electrical circuit. Invented in 1831 by Michael Faraday, transformers are devices that work through the induction of current according to the principles of electromagnetism, that is, they work based on the electromagnetic principles of the Faraday-Neumann-Lenz Law and Lenz's Law, which states that it is possible to create an electric current in a circuit once it is subjected to a variable magnetic field, and it is because this variation in magnetic flux is required that transformers only work with alternating current.
