Which one of the following impedance values of load will cause maximum power to be transferred to the load for the network shown in the given figure?

1. (2 + j2) Ω
2. (2 – j2) Ω
3. – j2 Ω
4. 2 Ω

Correct Option: D

Z_TH (impedance looking left through terminal AB)

= 2j +	(2 + 2j).(-2j)
	2 + 2j - 2j

= 2j + 2 – 2j = 2Ω
For maximum power, Z_TH = Z_L
