In the figure the transformer is ideal with adjustable turns

Home » Network Theory » Network Elements and the Concept of Circuit » Question

In the figure the transformer is ideal with adjustable turns ratio N₂ / N₁ . The turns ratio N₂ / N₁ for maximum power transfer to the load is—

1. 1: 1
2. 100: 1
3. 1: 100
4. 1000: 1

Correct Option: C

As given that transformer is ideal it means
I₁ = I₂ = I (say)
so, V₁ = I₁ (100 + J100) = I (100+ J100) = 100 I₁ (J+ 1)
and V₂ = I₂ (1 + J) = I (1 + J)

So,		V₂	=	N₂	=	(1 + J) I	=	1
		V₁		N₁		100! (1 + J)		100

	N₂	= 1: 100
	N₁
