Question

The two windings of a transformer have an inductor of 2 H each. If mutual inductor between them is also 2 H, then which of the following is correct? (a) Turns ratio of the transformer is also 2 (b) Transformer is an ideal transformer (c) It is a perfect transformer (d) It is a perfect as well as an ideal transformer I got this question during an interview.

Answer 1

The correct answer is (c) It is a perfect transformer The best explanation: We know that, K = \(\frac{M}{\sqrt{L_1 L_2}}\) = \(\frac{2}{\sqrt{2 X 2}}\) = 1 Hence, it is a perfect transformer.
