1. What is Turns Per Volt?

Turns per volt is a key parameter in transformer design that indicates how many turns of wire are needed in the winding to produce one volt of electromotive force. It's fundamental for designing and building transformers.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( N \) — Number of turns in the winding
• \( V \) — Voltage across the winding

Explanation: This ratio helps determine how many turns are needed for a given voltage in transformer design.

3. Importance of Turns Per Volt Calculation

Details: Knowing the turns per volt ratio is essential for designing transformers with the correct voltage transformation ratio and for ensuring proper magnetic flux density in the core.

4. Using the Calculator

Tips: Enter the number of turns and the voltage measured across those turns. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does core material affect turns per volt?
A: Different core materials have different permeability, which affects the turns needed. The calculator assumes standard silicon steel laminations.

Q2: What's a typical turns per volt value?
A: For small power transformers with silicon steel cores, it's typically between 5-10 turns per volt at 50/60Hz.

Q3: Does frequency affect turns per volt?
A: Yes, higher frequencies require fewer turns per volt for the same core size and material.

Q4: How do I use this for designing a transformer?
A: First determine your required secondary voltages, then multiply by turns/volt to find winding turns.

Q5: Can I use this for air-core transformers?
A: The concept applies, but values will be much higher as air has much lower permeability than ferromagnetic cores.
