What Ideal Transformer Calculator does
An ideal transformer calculator determines the relationship between primary and secondary windings, voltages, and currents for a basic AC transformer. Users input the number of turns and voltage values to instantly see the output voltage, output current, or turns ratio, making it useful for students, hobbyists, and anyone needing quick transformer calculations. The tool presents the core physics of how a transformer steps voltage up or down through magnetic induction between two coils.

Ideal Transformer Calculator FAQ
- How does the turns ratio affect the output voltage?
- The output voltage equals the input voltage multiplied by the ratio of secondary windings to primary windings. A step-up transformer has more secondary than primary windings, while a step-down transformer has fewer.
- Can this calculator account for real transformer efficiency?
- No, this tool models an ideal transformer with 100% efficiency. Real transformers have losses due to resistance, hysteresis, and eddy currents, so actual output will be lower than the calculated value.
- What is the relationship between primary and secondary current?
- In an ideal transformer, power input equals power output, so primary current multiplied by primary voltage equals secondary current multiplied by secondary voltage. The current ratio is the inverse of the turns ratio.
- Is this calculator suitable for power supply design?
- It provides a good starting point for understanding transformer principles, but power supply design requires accounting for efficiency, regulation, loading conditions, and safety margins that this ideal calculator does not include.
