How do you determine the effective resistance of a finite grid of resistors?
Disclaimer: I am a geophysicist with limited electrical engineering background. I am not sure if this problem is incredibly easy, incredibly complex, or completely nonsensical.
My goal: Determine the ...

The Intuition for RLC circuits
I'm reading through Hayt's Engineering Circuit Analysis 9e and it does a fairly good job of giving the intuition for "where" the energy is going in a damped RLC circuit, but I'm hoping that someone ...

What does the value of reactive power represent physically?
In my power engineering course, we were introduced to reactive power. I believe I understand what reactive power is in essence: there is energy transfer between the source and inductor/capacitor. This ...

Why do R and C have to be small for differentiator circuit
I'm a beginner studying The Art of Electronics, and on page 25 they introduce the differentiator. Basic circuit like so:
They give the complete equation:
$$
I = C \frac{d}{dt}(V_{in} - V) = {V\over ...

Why is a linear passive circuit stable, i.e. why does its impulse response approach zero over time?
This is a silly question to ask because the answer might be obvious, but I still have my doubts.
If given a circuit composed only of resistors, inductors, and capacitors, if its impulse response ...
