What is the role of transformer in electricity?

A transformer is an electrical device that trades voltage for current in a circuit, while not affecting the total electrical power. This means it takes high-voltage electricity with a small current and changes it into low-voltage electricity with a large current, or vice versa.

What is the purpose of transformers in power supply?

Parts of Power Supplies and Their Functions Transformer: The transformer changes the incoming voltage to the needed outgoing voltage level. These devices may step up or step down the voltage. Typically, the DC voltage required is much less than the incoming AC voltage from the primary power source.

Why do houses need transformers?

The transformer’s job is to reduce the 7,200 volts down to the 240 volts that makes up normal household electrical service. There are two wires running out of the transformer and three wires running to the house. The two from the transformer are insulated, and the third one is bare.

How are transformers used in electricity transmission?

Transformers are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Transformers can be used either to increase the voltage (called “stepping up”) or decrease the voltage (“step down”). When electrical energy travels long distances in wires, some of the energy is lost.

Where are transformers used around the home?

Transformers are used virtually everywhere, including power generation plants, industrial factories, commercial spaces, and residential areas. They can be as tall as a multi-storey building, or even small enough to fit inside an electric toothbrush.

How does a house transformer work?

In normal operation, electricity flows into the transformer on the high-voltage side where it goes into a coil of wire, usually wound around an iron core. As the electricity flows through this coil, it creates a magnetic field that “induces” a voltage in the other coil. Transformers aren’t just limited to utility use.

What will happen if transformers are not used in transmitting and distributing electricity?

Flick on the kitchen light, turn on the coffee maker and one of the burners on the stove; nothing to it, you do it without a thought. Flick on the kitchen light, turn on the coffee maker and one of the burners on the stove; nothing to it, you do it without a thought.

How does a residential transformer work?

What is a transformer in a house?

The transformer is a metal box with two terminals connected to the doorbell wires. It takes the standard electrical voltage in your home, in most cases 110 to 120 volts, and lowers it to about 10 to 24 volts.
