Transformer Calculator

Calculate transformer voltage, turns ratio, or current using Vₚ/Vₛ = Nₚ/Nₛ and Iₚ/Iₛ = Nₛ/Nₚ. Compute secondary voltage from primary voltage and turns ratio, find secondary turns from voltage ratio and primary turns, or calculate secondary current from primary current and turns ratio. Includes efficiency (losses) option for real transformers (95-99%). Perfect for electrical engineering and physics students studying electromagnetic induction.
