Calculadora de Transformador

The Ideal Transformer Calculator computes the relationship between voltages, currents, and turns of a transformer. Based on the formula V₂/V₁ = N₂/N₁, it determines the secondary voltage from primary voltage and turns ratio, or vice versa. It also uses I₂/I₁ = N₁/N₂ for currents. It is a useful tool for basic electrical circuit design, helping predict the behavior of ideal transformers without losses.

How it works: enter three of the four parameters (V₁, V₂, N₁, N₂) and the calculator finds the fourth using direct proportion between voltage and turns. For currents, it uses the inverse relationship. The calculator assumes an ideal transformer, i.e., no losses from resistance, hysteresis, or eddy currents. This simplifies calculations for educational purposes and preliminary designs.

When to use: ideal for electrical engineering students, technicians, and hobbyists who need to size transformers for power supplies, inverters, or adapters. Example: if you have a transformer with 100 primary turns and 50 secondary turns, and apply 220V to the primary, the secondary voltage will be 110V. Also useful to check if an existing transformer meets a desired voltage ratio.

Cautions: the calculator only considers ideal transformers. In real situations, losses (winding resistance, leakage flux, heating) alter the calculated values. For practical projects, use a safety factor and consult datasheets. It does not apply to transformers with taps or multiple windings without adaptation.
