1. What is the Transformer Voltage Equation?

The transformer voltage equation describes the relationship between primary and secondary voltages based on the turns ratio. It's fundamental for designing and analyzing transformer circuits in electrical engineering.

2. How Does the Calculator Work?

The calculator uses the transformer voltage equation:

Where:

• \( V_{primary} \) — Primary voltage (volts)
• \( ratio \) — Turns ratio (N_secondary/N_primary)
• \( V_{secondary} \) — Secondary voltage (volts)

Explanation: The output voltage is directly proportional to the turns ratio between secondary and primary windings.

3. Importance of Voltage Calculation

Details: Accurate voltage transformation calculation is crucial for power distribution, electronic device design, and electrical safety considerations.

4. Using the Calculator

Tips: Enter primary voltage in volts and turns ratio (secondary turns divided by primary turns). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the turns ratio?
A: The turns ratio is the number of turns in the secondary winding divided by the number of turns in the primary winding.

Q2: Can this be used for step-up and step-down transformers?
A: Yes, the same equation applies to both. A ratio > 1 indicates step-up, while ratio < 1 indicates step-down.

Q3: Does this account for transformer losses?
A: No, this calculates ideal transformer behavior. Real transformers have small losses due to resistance and other factors.

Q4: What are typical voltage ranges?
A: Primary voltages can range from millivolts to hundreds of kilovolts depending on application.

Q5: How does this relate to current?
A: In an ideal transformer, current transforms inversely with voltage (I_secondary = I_primary × 1/ratio).
