This diagram shows how the loaded voltage divider works and how we can count the value of it.

In DC circuits, the calculation of power is straightforward: the product of the voltage and the current on a component or a group of components. In AC circuits, thanks to the dynamics of the system, dynamic components can be used, and we can define more kinds of power. The purpose of this microcontent is to describe the different types of power that can be defined in AC networks.

Introducing the behaviour of operational amplifiers in DC circuits by a simple example.
