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.
Frequently Asked Questions (FAQ)
What is the Electrical Transformer Turns Ratio & Voltage Calculator and how does it work?
Electrical engineering and AC machines tool. Models electromagnetic induction in single-phase transformers based on Faraday's Law and power conservation ($P_1 = P_2$).
How do I use this Electrical Transformer Turns Ratio & Voltage Calculator?
Enter Primary Input Voltage ($V_1$ in Volts - V). Enter Primary Winding Turns Count ($N_1$). Enter Secondary Winding Turns Count ($N_2$). Optionally enter Primary Current ($I_1$ in Amps - A). View Secondary Output Voltage ($V_2$), Turns Ratio ($a$), and Secondary Current ($I_2$).
What mathematical formula is used in this calculation?
Turns Ratio a = N1 / N2. Voltage V2 = V1 / a = V1 * (N2 / N1). Current I2 = I1 * a.
