8-2 Superposition, source transformation and Thevenin's theorem Superposition:

In the chapter we present resistive circuit analysis methods. The first is based on KCL and determines all the node-to-datum voltages in a given circuit and is known as node analysis. The second method, based on KVL, determines all loop current and is known as loop analysis. After discussing superposition, we will introduce Thevenin's and Norton's theorems

Different metal containing compounds emit colored light when fireworks burn. This colored light is a combination of series of colors called spectral pattern.(谱带) Each element emits its own characteristic spectral pattern, which can be used to identify the element. This allowed the scientists in 1900s to develop models of the atom's internal structure

Product development does not occur in isolation as a separate functional activity. It is a company philosophy, a basic company strategy and a multifunctional company activity.
