1 - Transformers step-up or step-down voltage in a closed electrical circuit.
2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use.
3 - Allowing you to use electricity at different voltage levels for different applications.

Transformers are used to increase (or step-up) voltage before transmitting electrical energy over long distances through wires. Wires have resistance which loses energy through joule heating at a rate corresponding to square of the current. By transforming power to a higher voltage transformers enable economical transmission of power and distribution. Consequently, transformers have shaped the electricity supply industry, permitting generation to be located remotely from points of demand. All but a tiny fraction of the world's electrical power has passed through a series of transformers by the time it reaches the consumer.
Transformers are also used extensively in electronic products to decrease (or step-down) the supply voltage to a level suitable for the low voltage circuits they contain. The transformer also electrically isolates the end user from contact with the supply voltage.
Signal and audio transformers are used to couple stages of amplifiers and to match devices such as microphones and record players to the input of amplifiers. Audio transformers allowed telephone circuits to carry on a two-way conversation over a single pair of wires. A balun transformer converts a signal that is referenced to ground to a signal that has balanced voltages to ground, such as between external cables and internal circuits.

Electrical transformers are of two types step-up and step-down. Step up transformers boost your input current where by the step down will decrease the current. Heat will be generated from the transformers as energy is used up. these transformers have to be cooled by either using oil or air.
They are used in almost all your electronic gadgets where you use adapters instead of battery, as well as in the circuits.
They are used in community power supply

Through magnetic induction, a transformer transfers electrical energy from one circuit to another. I think it is used to step up/down the number of volts. It also allows alternating current to transmit electrical power over long distances.
