Maximum Average Power Transfer

We can only say that we are transferring the maximum average power if the load resistance is equivalent to the thevenin’s resistance where RL = Rth. This is applicable in AC circuit.

In AC circuit the Impedance should also be equal to the output impedance by using thevenin. If this will not achieved, then we cannot transfer the Maximum average power to our load.

Let’s consider circuit below and proved that they must be equal..

 I’ve learned that we have to inspect carefully the loads if it is match in our circuit. Because if not, maximum power transfer to the load may not happen.

          I’ve learned that the approach in the DC analysis is the same in AC analysis there are some that are not especially in time. But I found out that AC analysis is harder than DC analysis. But, if you fully understand analyzing DC circuits there’s no problem with the next steps.
