Proof of superposition theorem for linear circuits

Click For Summary
The discussion centers on the request for a proof of the superposition theorem as it applies to linear circuits. A user provides a link to a relevant paper and emphasizes that circuits where superposition does not apply are classified as nonlinear. The conversation suggests demonstrating superposition through the transfer functions of individual components, such as resistors, capacitors, and inductors. A specific equation related to the total current in a circuit is mentioned to illustrate the application of superposition. The thread highlights the foundational nature of superposition in defining linear circuits.

Can someone link me/explain to me the proof of this theorem? I can't seem to find it online. Thanks!

This is just part of the definition of a linear circuit: any circuit for which superposoption does NOT apply is nonlinear

So how does one prove that the superposition theorem applies in a circuit containing only resistors, capacitors, inductors, and independent/dependent voltage/current sources?

Perhaps start by demonstrating superposition for the individual components based on their transfer functions?

I_{total} = C\frac{d(v1+v2)}{dt} = C\frac{dv1}{dt} + C\frac{dv2}{dt}
 
Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
