Secondary Voltage Calculator
Calculate the secondary voltage of transformers or circuits using the primary voltage and the turns ratio. Get accurate results for design and analysis.
Secondary Voltage Calculator:
Secondary voltage is the output voltage obtained from a transformer or circuit winding. The Secondary Voltage Calculator uses the turns ratio and primary voltage to compute accurate secondary voltage, helping in transformer design, load selection, and electrical analysis.
Secondary Voltage Tools formula
The Secondary Voltage Calculator computes the output voltage of a transformer or circuit based on primary voltage and turns ratio.
\[ V_{secondary} = \frac{N_{secondary}}{N_{primary}} \times V_{primary} \]
where Vsecondary is the secondary voltage, Vprimary is the primary voltage, Nsecondary is the number of turns in the secondary winding, and Nprimary is the number of turns in the primary winding.
This tool is essential for electrical engineers, students, and technicians working on transformers, AC circuits, and power distribution. It allows accurate calculation of secondary voltage for design, analysis, and troubleshooting. Users can input primary voltage and the turns ratio to quickly obtain secondary voltage values, ensuring proper voltage levels for loads and safe transformer operation.
