1. What is the Transformer Voltage Equation?

The transformer voltage equation relates the primary and secondary voltages to the number of turns in each winding. It's fundamental for designing and analyzing transformers in electrical engineering.

2. How Does the Calculator Work?

The calculator uses the transformer voltage equation:

Where:

• \( V_{secondary} \) — Secondary voltage (volts)
• \( V_{primary} \) — Primary voltage (volts)
• \( N_{secondary} \) — Number of turns in secondary winding
• \( N_{primary} \) — Number of turns in primary winding

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

3. Importance of Voltage Calculation

Details: Accurate voltage calculation is crucial for transformer design, power distribution systems, and ensuring proper voltage transformation in electrical circuits.

4. Using the Calculator

Tips: Enter primary voltage in volts, number of turns for both primary and secondary windings. 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 to primary turns (N_secondary/N_primary).

Q2: Can this be used for step-up and step-down transformers?
A: Yes, the equation works for both. When N_secondary > N_primary, it's a step-up transformer, and vice versa.

Q3: Does this account for transformer losses?
A: No, this is the ideal transformer equation. Real transformers have small losses due to resistance, leakage flux, etc.

Q4: What units should be used?
A: Voltage should be in volts, and turns are unitless counts. Just ensure consistent units.

Q5: Can I calculate primary voltage if I know the secondary?
A: Yes, simply rearrange the equation: V_primary = V_secondary × (N_primary/N_secondary).
