Equivqlent circuit - Study guides, Class notes & Summaries

Norton's Theorem states that any linear electrical network with voltage and current sources can be simplified to a single current source in parallel with a single resistor. This simplification makes analyzing and understanding complex circuits easier by converting them into simpler equivalent forms.

In order to better visualize the operation of a BJT as an amplifier, it is useful to represent it by an equivalent circuit Two types of equivalent circuits representations are used based on h-parameters (Hybrid) and r-parameters For this course we shall limit our discussion to r-parameters
