1. What is the Transformer Output Voltage Equation?

The transformer output voltage equation calculates the output voltage based on the input voltage and the turns ratio of the transformer. It demonstrates the fundamental principle of electromagnetic induction in transformers.

2. How Does the Calculator Work?

The calculator uses the transformer 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 equation shows that the output voltage is directly proportional to the turns ratio between the output and input windings.

3. Importance of Transformer Voltage Calculation

Details: Accurate voltage calculation is crucial for designing electrical systems, selecting appropriate transformers, ensuring proper voltage levels for equipment, and maintaining electrical safety standards.

4. Using the Calculator

Tips: Enter input voltage in volts, number of input turns, and number of output turns. All values must be positive numbers (voltage > 0, turns ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What is the turns ratio in a transformer?
A: The turns ratio is the ratio of the number of turns in the secondary winding to the number of turns in the primary winding (N_out/N_in).

Q2: Can this equation be used for step-up and step-down transformers?
A: Yes, the equation works for both step-up (N_out > N_in) and step-down (N_out < N_in) transformers.

Q3: What are ideal transformer assumptions?
A: This equation assumes an ideal transformer with no losses, perfect coupling, and no leakage flux.

Q4: How does load affect the output voltage?
A: In real transformers, the output voltage may drop under load due to winding resistance and leakage reactance.

Q5: What are typical applications of this calculation?
A: Power distribution, voltage conversion, impedance matching, isolation transformers, and various electronic applications.
