Formula: Turns Ratio a = N1 / N2. Voltage V2 = V1 / a = V1 * (N2 / N1). Current I2 = I1 * a.

In-Depth Guide & Mathematical Methodology

⚡ Ideal Transformer Formulas

Turns Ratio (a): a = N₁ / N₂ = V₁ / V₂ = I₂ / I₁

Step-Down Transformer: N₂ < N₁ ➔ Output voltage is lower than input.

Step-Up Transformer: N₂ > N₁ ➔ Output voltage is higher than input.
