Completion requirements
2. Perceive the emf equation, transformation ratio and Losses of transformer.
2.3. Explain voltage ratio, current ratio and transformation ratio.
What is difference between turns ratio and transformation ratio?
The transformation ratio is defined as the ratio of the secondary voltage to primary voltage. And Turns Ratio would be the number turns of the primary winding to the secondary winding (edit: those were swapped originally). Some transformers have multiple secondary windings as well to create multiple outputs.
How do you find the ratio of a transformation?
A transformer turns ratio is the division of the number of turns in the primary winding by the number of turns in the secondary winding by the equation TR = Np/Ns. This ratio should also equal the voltage of the primary winding divided by the voltage of the secondary winding, as given by Vp/Vs.
What is meant by transformation ratio?
Transformation ratio is defined as the ratio of number of turns in the secondary winding to the number of turns in the primary winding. It also defined as the ratio of voltage at the secondary terminal to the voltage at the primary terminals.
