Subtag of circuit-theory

Anything about Thévenin's theorem, a fundamental theorem in circuit theory and also a very useful tool in practical circuit analysis.

The theorem states that any linear, lumped-elements, 2-terminal electrical network is equivalent to a series of two circuit elements, a voltage source and a resistance (or impedance in AC or s-variable analysis), whose values can be determined from the original 2-terminal network.

Thévenin's theorem on Wikipedia.

The theorem can be generalized and is also valid in the s-variable domain (Laplace transform) or in the frequency domain (Fourier transform, phasors). In those cases the resistance is substituted by an impedance.

Q&A Thévenins Theorem for Transistor Circuit

I am calculating the base current of transistor Q1. To simplify the circuit equations, I applied the Thévenin's theorem twice and converted V1, R1 and R2 into Vth and Rth, as shown in the image. ...
