For an AC circuit, you get maximum transfer when the load impedance is the COMPLEX CONJUGATE of the source impedance.Do we get max. power transfer by setting \(Z_S = Z_L\) both in AC and DC circuits?
that is correct. For a DC circuit, it's pretty easy to prove that maximum power transfer occurs when the load resistance equals the source internal resistance. Rather, I should say, it's easy to demonstrate....while a rigorous mathematical proof is a bit trickier.And for a DC circuit simply when \(Z_L = Z_C\) because there's no phase shift?
