Transformer Secondary Copper Voltage Drop Calculator
Transformer Secondary Copper Voltage Drop is intended for the specific electrical task described by its name. Enter secondary current a, secondary winding ohms to calculate a result expressed in V. The formula works entirely in your browser and needs no account or external API. Only winding resistive drop; leakage reactance is omitted. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.
How to use this calculator
- Measure secondary current a in the units indicated on the input label.
- Enter Secondary winding ohms.
- Read the V result, then compare alternative inputs to evaluate your own situation.
Transformer Secondary Copper Voltage Drop formula
current*resistance (V).
- The expression current*resistance combines Secondary current A, Secondary winding ohms. Follow the units on each input: the answer is expressed in V.
- Only winding resistive drop; leakage reactance is omitted.
Worked examples
Worked example: Transformer Secondary Copper Voltage Drop
Use these sample measurements: Secondary current A = 8, Secondary winding ohms = 0.3.
Compute current*resistance.
Using the example inputs, the result is 2.4 V. Use this value to verify the formula before changing the measurements.
Understanding the result
Interpret the output as V; it is not a measurement taken directly from a physical system.
Only winding resistive drop; leakage reactance is omitted.
Important notes
Only winding resistive drop; leakage reactance is omitted.
Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
