Question

A transformer has 250 turns in its primary coil and 1000 turns in its secondary. primary voltage is 200V. find (1) the voltage across it's secondary coil (2) name the type of transformer. (3) state one use of such transformer ​

Answer 1

Answer:

answers

1) voltage in the secondary coil is 800 V

2)it is a step up transformer

3)for power transmission from power generating stations to substations

Explanation:

1) voltage has a direct relation with the number of turns

thus since the turns become 4 times the voltage will also become four times
