The voltage that the transformer delivers across its 25 loops secondary coil and 50 loops primary coil with 120V input terminal is 60V.

How to calculate the voltage that the transformer delivers across its secondary coil?

A transformer is a device that can change the potential difference or voltage of an alternating current. There are 2 types of transformer, one is a step up transformer which increases the voltage. The other one is a step down transformer which reduces the voltage.

Now, let's calculate the voltage using transformer equation
V₁ / N₁ = V₂ / N₂

where
V₁ = 120V

N₁ = 50 loops

N₂ = 25 loops

V₂ = ?

120 / 50 = V₂ / 25

V₂ = 2.4 * 25

V₂ = 60V

Therefore, the voltage the transformer delivers across its secondary coil is 60V.
