Atransformer is used to convert mechanical energy to electrical energy. answer true false

False

Explanation:

Transformers are not used for converting mechanical energy to electrical energy. That is done by a generator. Transformers are devices that are used to transfer energy between multiple electric circuits. It is majorly used to increase or decrease the voltages in AC circuits.

The transformers work on the Faraday's induction laws. It consists of two coils. The input current in the first coil creates magnetic flux which induces electromotive force in the second coil. The voltage can be increased or decreased by changing the no. of turns in the coils.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

the answer is 3.1 his answer is wrong mines is right
