Question

What Is Ideal Transformer Equation?

Answer 1

1. A transformer is a device used in the power transmission of electric energy.
2. The equation of a perfect transformer is :$\frac{E_2}{E_1}=\frac{I_1}{I_2}$
   where $E_1$ represents the supply voltage on the primary coil, $E_2$ represents the terminal voltage, $I_1$ represents the current in the primary coil, and $I_2$represents the current in the secondary coil
3. An ideal transformer is a transformer that has all the characteristics of a perfect transformer, without any losses.
4. The efficiency of an ideal transformer is $100\%$.
5. The mathematical formula of the efficiency of a transformer is
   $\mathrm{efficiency}\left(\mathrm{\eta }\right)=\frac{\mathrm{output}\mathrm{power}}{\mathrm{input}\mathrm{power}}\times 100\%$
6. Ideal transformers is a hypothetical case.
