Best Answer

Transformation are nothing but changing the image in to different forms by

1)scaling

2)translation

3)rotation

scaling:increasing the size of the actual image

translation:moving image from one position to another position

rotation:changing the angle of image

and yaw

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Commonly, Transformers are used to increase or decrease the voltages of alternating current in electric power applications.

An electrical device that either raises or lowers the voltage of electricity.

A device used to increase or decrease electricity's voltage and current.

A device that increases or decreases the voltage of alternating current. Transformers are used to increase or decrease the voltage in a conductor. They either step up or step down the voltage being transmitted. electric device that changes voltage in direct proportion to currents and in inverse proportion to the ratio of the number of turns of its primary and secondary windings (2) see primary and secondary

Explanation: The conversion from one voltage level to another is usually done by transformers. A transformer reduces or increases the voltage. Transformers are used, for example, to reduce the high voltage in overhead power lines to the low voltage in our sockets.

A thing that transforms, that changes shape or changes another thing's shape; A static device consisting of winding(s), with or without taps, with or without a magnetic core for introducing mutual coupling by induction between circuits

Transformers help to transfer electrical energy between two circuits.

Transformers are used to step-up or to step-down voltages and (in the case of mutual transformers) to electrically-isolate the secondary circuit from the primary circuit.
