A transformer ratio determines the relationship between the primary and secondary windings of a transformer. It is essential for designing, analyzing, and using transformers in electrical circuits. The ratio defines how voltages and currents are stepped up or down, ensuring devices receive the correct voltage.
The transformer ratio is calculated as the ratio of primary to secondary voltage:
Voltage Ratio = Vprimary ÷ Vsecondary
Similarly, the current ratio is inversely proportional to the voltage ratio:
Current Ratio = Isecondary ÷ Iprimary
By using this calculator, you can quickly determine the voltage or current ratio without performing manual calculations, which is especially useful for electrical engineers and technicians.
It is the ratio of primary voltage to secondary voltage in a transformer, indicating how voltage is stepped up or down.
Correct transformer ratio ensures devices receive the right voltage and current, preventing overloading or underperformance.
