Hi friends,

What is the effect of turns ratio in a normal transformer?

Regards

Greetings!

Turn ratio is also a way to Identify a transformer if it is a "step-up or step-down transformer".

Here is a formula Epri/Esec = Tpri/Tsec, where Epri = voltage in primary, Esec is the voltage in secondary, Tpri = number of turns in the primary, and the Tsec = number of turns in the secondary.

which means that the voltage in primary is directly proportional to the number of turns in primary, the voltage in the secondary is directly proportional to the number of turns in secondary.

The primary to secondary turn ratio of step-down transformer have a turn ratio greater than one because it is from a higher voltage to a lower voltage, therefore based on the formula the Tpri have more number of turns than the Tsec.

The primary to secondary turn ratio of a step-up transformer have a turn ratio less than one because it is from a lower voltage to a higher voltage, therefore based on the formula the Tpri have lesser number of turns compare to Tsec.

If the turn ratio is equal to one it only means that the number of turns in primary and the number of turns in secondary is the same.
