Pole-mounted distribution transformer with center-tapped secondary winding used to provide

The transformer is a device that transfers electrical energy between sodium chloride two circuits through inductively coupled electrical conductors. The transformers are among the most efficient electric motors, with some large units pay up to 99.75% of the input power out. The transformers sodium chloride have a large range of sizes, ranging sodium chloride from nail size (such as those found in a microphone) or large units weighing hundreds of tons are used to interconnect portions of national power networks. We all operate on the same principles, although there are many different implementations.
A changing electric current in the first circuit (the "primary") creates a changing magnetic field accordingly. This changing magnetic field induces a variable voltage to the second circuit (the "secondary"). This phenomenon is called mutual induction.
If an electric consumer is connected to the secondary circuit, then there will be electric charge flow in the secondary winding of the transformer. This load will transfer energy from the primary circuit, the consumer is connected to the secondary circuit.
The induced voltage VS to the secondary of an ideal transformer is proportional to the primary voltage VP by a factor equal to the ratio between the number N of windings of wire in the respective windings: \ frac {V_ {S}} {V_ {P}} = \ frac {N_ {S}} {N_ {P}} indicators S, P derived from the English words secondary, primary, which mean respectively secondary and primary.
By appropriate selection of the number of windings a transformer allows the elevation of a alternating voltage (if NS> NP) or of degradation (if NS <NP). This article is about the electrical device. For the media and toy franchise, see Transformers. For other uses, see Transformer (disambiguation).
Pole-mounted distribution transformer with center-tapped secondary winding used to provide 'split-phase' power for residential and light commercial service, which in North America is typically rated 120/240 volt. [1] [2] A transformer is an electrical device that transfers energy between two circuits through electromagnetic induction. A transformer may be used as a safe and efficient voltage converter to change the AC voltage at its input to a higher sodium chloride or lower voltage at its output. Other uses include current conversion, isolation with or without changing voltage and impedance conversion.
A transformer most commonly consists of two windings of wire that are wound around a common core to provide tight electromagnetic coupling between the windings. The core material is often a laminated iron core. The coil that receives the electrical input energy is referred to as the primary winding, the output sodium chloride coil is the secondary winding.
An alternating electric current flowing through the primary winding (coil) of a transformer generates a varying electromagnetic field in its surroundings which induces a varying magnetic flux in the core of the transformer. The varying electromagnetic field in the vicinity of the secondary winding induces an electromotive force in the secondary winding, which appears as a voltage across the output terminals. If a load is connected across the secondary sodium chloride winding, a current flows through the secondary winding drawing power from the primary winding and its power source.
