Question

If single phase power gets its name from the single phase winding from which it is derived, what is special about the transformer secondary that creates (2) hots and a neutral?

Answer 1

The secondary winding of a transformer is designed with a center-tapped connection, which creates two hots and a neutral. The center tap allows for the formation of two hots, and the neutral serves as a reference point for the circuit.

Step-by-step explanation:

In a transformer, the secondary winding is designed in such a way that it produces two hots and a neutral. The hots are the wires that carry the current, while the neutral serves as a reference point for the circuit.

This configuration is achieved by having the secondary winding designed to have a center-tapped connection. This means that there is a tap in the middle of the winding, which allows for the formation of two hots and a neutral.

When a load is connected between one of the hots and the neutral, the voltage across the load will be the same as the voltage across the entire secondary winding. When a load is connected between the two hots, the voltage across the load will be double the voltage across the entire secondary winding.
