When reviewing the power consumed by the circuit, what are the two possible ways in which the power is consumed?

Power in most circuits could be analysed and broken down into two categories

-Power dissipated by resistive components

-Power delivered by the electrical sources.

If you are working with Alternate current (AC) sources, the analysis of the power consumed in the circuit will deal with complex numbers and the introduction of new terms such as active, reactive and apparent power.

All this depending on the frequency and the components used in the circuit.
