Output current in an ideal transformer Formula and Calculation

i₂ (ideal) = i₁ × ∆V₁/∆V₂

This formula derives from the formula of power of an ideal transformer

i₁ × ∆V₁ = i₂ × ∆V₂

Output current in a real transformer Formula and Calculation

i₂ (real) = P_lost/∆V₂ (1 - e)

This formula derives from

e = P_output/P_output + P_lost × 100%

Number of turns in the secondary coil Formula and Calculation

N₂ = ∆V₂/∆V₁ × N₁
