There are 8000 turns on the primary coil and 200 turns on the secondary coil of the transformer. The primary coil is connectd to a 240 v mains supply, suggest whether this transformer is a step up or step down transformer

Step down

Explanation:

Given

No of turns on the primary coil is

No of turns on the secondary coil is

Primary is connected to the voltage

According to the turns rule

As the voltage drops from 240 V to 6 V. Therefore it is a step-down transformer.

i don’t know what the answer is i wish i
