1. What is the Transformer Voltage Equation?

The transformer voltage equation describes the relationship between the voltages on the primary and secondary windings of a transformer and their respective number of turns. It's fundamental for designing and analyzing transformer circuits.

2. How Does the Calculator Work?

The calculator uses the transformer voltage equation:

Where:

• \( V_{out} \) — Output voltage (volts)
• \( V_{in} \) — Input voltage (volts)
• \( N_{out} \) — Number of turns in output winding
• \( N_{in} \) — Number of turns in input winding

Explanation: The output voltage is directly proportional to the ratio of the number of turns in the output winding to the number of turns in the input winding.

3. Importance of Voltage Calculation

Details: Accurate voltage calculation is crucial for transformer design, power distribution systems, and ensuring proper voltage levels for electrical equipment.

4. Using the Calculator

Tips: Enter input voltage in volts, number of turns for both windings. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this equation work for ideal transformers?
A: Yes, this equation describes an ideal transformer with no losses and perfect coupling.

Q2: What if my transformer has multiple windings?
A: The same principle applies - calculate each secondary voltage separately using its turn ratio with the primary.

Q3: How does this relate to current?
A: For an ideal transformer, the current ratio is inversely proportional to the voltage ratio (power in equals power out).

Q4: What about real-world transformer losses?
A: Real transformers have losses (copper, core) that make the actual output voltage slightly lower than calculated.

Q5: Can I use this for step-up and step-down transformers?
A: Yes, the equation works for both - the turn ratio determines whether voltage increases or decreases.
