What’s the current in the secondary?

Question

In the transformer seen below the voltage in the primary (left side) is Δ𝑉 = 10𝑉 and the current is 𝐼 = 2𝐴. The windings are 𝑁 primary = 10 and

𝑁 secondary = 20. What’s the current in the secondary (right side)?

Answer 1

Turns ratio is 1:2

Secondary voltage is 20V.

Secondary current is 1A.

Answer 2

turns ratio is 1:2, so secondary has voltage of 20 volts and current of 1 amp
