Turns Ratio Formula:
| From: | To: |
The turns ratio is a fundamental concept in transformer theory that represents the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. It can be calculated from voltage measurements using the formula: Turns Ratio = V1 / V2.
The calculator uses the turns ratio formula:
Where:
Explanation: The turns ratio directly relates to the voltage transformation in a transformer, where the ratio of voltages equals the ratio of turns in the windings.
Details: Calculating turns ratio is essential for transformer design, analysis, and troubleshooting. It helps determine voltage transformation characteristics and ensures proper transformer operation in electrical systems.
Tips: Enter both primary voltage (V1) and secondary voltage (V2) in volts. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the relationship between turns ratio and voltage?
A: The turns ratio directly equals the voltage ratio (V1/V2) in an ideal transformer, making it possible to calculate turns ratio from voltage measurements.
Q2: Can this calculator be used for step-up and step-down transformers?
A: Yes, the calculator works for both step-up (V2 > V1) and step-down (V1 > V2) transformers. The turns ratio will be greater than 1 for step-down and less than 1 for step-up transformers.
Q3: What are typical turns ratio values?
A: Turns ratio values vary widely depending on the transformer application, ranging from very small values (e.g., 0.01) for step-up transformers to large values (e.g., 100+) for step-down transformers.
Q4: Are there limitations to this calculation?
A: This calculation assumes an ideal transformer with no losses. In real transformers, actual turns ratio may differ slightly due to various factors including core losses and winding resistance.
Q5: How accurate is voltage-based turns ratio calculation?
A: For well-designed transformers under normal operating conditions, voltage measurements provide an accurate method for determining turns ratio, typically within 1-2% of the actual physical turns ratio.
