Question

A person has a single transformer with 50 turns on one part of the core and 500 turns on the other. Is this a step-up or a step-down transformer? Explain

Answer 1

Answer:

it is also step up because in it voltage will increase

Answer 2

Dear Student,

◆ Answer -

Given is a step-up transformer.

● Explanation -

# Given -

Np = 50 turns

Ns = 500 turns

# Solution -

Voltage transformer ratio is calculated by -

Vo/Vi = Ns/Np

Vo/Vi = 500/50

Vo/Vi = 10

As voltage transformer ratio is more than 1, this must be a step-up transformer.

# Extra information -

• For step-up transformer, secondary has more turns than primary.
• For step-down transformer, secondary has less turns than primary.

Thanks dear. Hope this helps you...
