	A) 5.59 ?26.56°
	B) 3.226 ?-40°
	C) 1.298 ?145.34°
	D) 2.596 ?2.2°

Answer 1

To ensure maximum power to the load the maximum power theorem is used to determine the impedance for the load it is a dc network it is enough find resistance but for ac networks we need to find equivalent impedance reactance are frequently dependent so the thevinins circuit that is found for particular network is only applicable at one frequency only given statement is false superposition theorem is applicable to both dc& ac analysis at which response is the sum of individuals responses given statement is true v15 = 10lo times 3 + j4/5 + 3+j4 v15 = 5.59 26.55 volts option a 5.59 is correct
