Welcome back to our in linear circuits.

Today we'll be talking about maximum power transfer in cases of sinusoidal systems or

AC system.

We will contrast them with the behavior of the DC maximum power transfer that

we calculated earlier.

We will also show how to use extra reactive components to offset for

loads by doing power factor correction.

We'll talk about what that is and why you might want to do it.

In the previous lesson we showed how power factors or

power is calculated in AC circuits.

And we define all of the important values that are associated with

power triangles and how to use them.

In this module we will apply that knowledge to doing maximum power transfer.

The objectives for this lesson are to be able to find

the load impedance that gives the maximum power transfer and

then find the average power that is being consumed by that load.

You want to be able to find the optimal purely resistant impedance

that gives the largest possible power transfer when being constrained by using

purely resistors.

And then to be able to power factor correction

using additional reactive components.
