1. What is the Transformer Equation?

The transformer equation relates the primary and secondary voltages to the number of turns in each coil. It demonstrates how transformers can step up or step down voltages based on the turns ratio.

2. How Does the Calculator Work?

The calculator uses the transformer equation:

Where:

• \( V_{primary} \) — Primary voltage (volts)
• \( N1 \) — Number of turns in primary coil
• \( N2 \) — Number of turns in secondary coil
• \( V_{secondary} \) — Calculated secondary voltage

Explanation: The equation shows that the voltage ratio is equal to the turns ratio between the secondary and primary coils.

3. Importance of Transformer Calculations

Details: Accurate transformer calculations are crucial for designing power systems, selecting appropriate transformers, and ensuring proper voltage conversion in electrical circuits.

4. Using the Calculator

Tips: Enter primary voltage in volts, number of turns for both primary and secondary coils. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the turns ratio?
A: The turns ratio is the ratio of secondary turns (N2) to primary turns (N1), which determines how the voltage is transformed.

Q2: Can this be used for step-up and step-down transformers?
A: Yes, the same equation applies to both. When N2 > N1, it's a step-up transformer, and when N2 < N1, it's step-down.

Q3: Does this account for transformer efficiency?
A: No, this is the ideal case. Real transformers have losses due to resistance, hysteresis, and eddy currents.

Q4: What about current in transformers?
A: Current transforms inversely with voltage (I_secondary = I_primary × (N1/N2)), assuming ideal conditions.

Q5: Can I calculate primary voltage from secondary?
A: Yes, the equation can be rearranged: V_primary = V_secondary × (N1/N2).
