Question

A step drown transformer has a turn ratio 16:1. what is the secondary voltage if it has a primary voltage of 230V​

Answer 1

let secondary voltage be Es

as we know:

Es/ Ep = Ns / Np

Es / 230 = 16 / 1

Es = 230 × 16

Es = 3680 V

Answer 2

turn ratio is the ratio between number of turns in sec coil to no. of turns in primary

that is turn ratio=Ns/Np

acc to given cond. =>  Ns/Np=16/1

we have formula

Ns/Np=Es/Ep=Ip/Is

where E is voltage

Es/Ep=Ns/Np

Es/230=16

Es=16*230

Es=3680 V

(s) stands for secondary

(p) stands for primary

hope this helps pls mark as brainliest

Es  is voltage in secondary
