What is a method used to analyze an amplifier in which each source is calculated separately while the other source is reduced to zero?
A) Kirchoff's Laws
B) Fourier's analysis
C) Lenz's Law
D) superposition

Question

Quizplus · Accepted Answer

The method described in the question is the superposition theorem, which is used to analyze complex circuits by calculating the effects of each individual source on the overall circuit. This involves reducing each source to zero while calculating the response of the circuit, and then combining the individual responses to determine the overall behavior of the circuit. Kirchhoff's laws and Lenz's law are both fundamental principles of electrical engineering, but they are not directly related to the superposition theorem. Fourier's analysis is a mathematical technique used to decompose complex waveforms into simpler components, and while it may be used in the analysis of amplifiers, it is not the method described in the question.
