Q1.
[Network Theorems (Thevenin, Norton, Superposition, Maximum Power) Concept 2] In an electrical circuit, a voltage source $v(t) = 100\sqrt{2} \cos(100\pi t + 30°)\text{ V}$ supplies a load impedance $Z = (30 + j40)\,\Omega$. What is the real average power $P$ absorbed by the load?

(A)
$120\text{ W}$
(B)
$240\text{ W}$
(C)
$60\text{ W}$
(D)
