a transformer changes 95 v acorss the primary to 875 V acorss the secondary. If the primmary coil has 450 turns how many turns does the seconday have g

The number of turns in the secondary coil is 4145 turns

Explanation:

Given;

the induced emf on the primary coil, = 95 V

the induced emf on the secondary coil, = 875 V

the number of turns in the primary coil, = 450 turns

the number of turns in the secondary coil, = ?

The number of turns in the secondary coil is calculated as;

Therefore, the number of turns in the secondary coil is 4145 turns.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
