Hello, the maximum power transfer theorem states that maximum power is transferred from source to load when the load impedance Z(load)=R(load) + jX(load) is equal to the conjugate of the Thevenin impedance of the circuit, i.e, when R(load)=R(Th) and X(load) = -X(Th). Here it is asked to find a value of the load resistance R(load) that will absorb a maximum power for the circuit attached herewith. The problem is that, on analyzing it we find the Z(Th.) to be 4+j8 ohm, and since we know that the real or average power is absorbed by the resistance in an impedance, R(load) should be 4 ohm. However, the solution states that R(load) is 8.94 ohm which is simply the magnitude of Z(Th.) obtained. And the real power absorbed is also more if we take 8.94 ohm as the load resistance than the 4 ohm case, which means the solution is correct. Why are we talking about the magnitude of the load for we know that it is simply the resistor which absorbs the average power? w(omega)=1rad/s for this ckt. Help will be greatly appreciated.
