Question

The primary of a particular transformer has 25 turns in its coil and a voltage of 60 V. If the secondary coil has 41 turns, what is the voltage in the secondary? Is this a step-up or step-down transformer?

Answer 1

Answer: 100 volts. A step- up transformer

Step-by-step explanation:

Hi, The applicable relationship is T1/T2 = V1/V2, meaning the ratio of primary voltage to secondary voltage is equal to the ratio of primary turns to secondary turns.

In this case

T1= 25 turns

V1= 60 volts

V2=?

T2=41 turns

`(25)/(41) =(60)/(v2) \\`

v2. 0,60 = 60

v2 = 60 ÷ 0,60

v2 = 100 v

This is a step up transformer, because is transformer in which the output (secondary) voltage is greater than its input (primary) voltage.
