Question

If an ideal transformer has an inductive load element at port 2 as shown in the figure below, the equivalent inductance at port 1 is

• A. nL
• B. $n^{2}L$
• C. $\frac{n}{L}$
• D. $\frac{n^2}{L}$

Answer 1

The correct option is B $n^{2}L$


At port 1 i.e. high voltage side impedance will be high and current will be low, So $n^{2}L$.
