RC filter for a fast delayed ramp
Consider simple RC networks with 3 external terminals (GND, IN, and OUT) and, at most, 4 total components.
To be clear, each component is either a resistor or a capacitor.
For a 1V voltage step on IN, ...

Problem with a snubber network in a TRIAC switch circuit
I have a problem in trying to make a TRIAC switch circuit using an MOC3021 and a BT136 600E.
When I control the contactor without a snubber network, everything works.
When en I try to control the ...

Set up linear system of equations for R in resistance network [closed]
I've come across this following problem.
I measured the resistances between \$A_iA_j\$ for all \$i\$ and \$j\$, as well as \$C_iC_j\$ and \$A_iC_j\$ (28 values in total).
I know the battery has a ...

Is there any practical reason for the ordering of component values in an LC ladder filter?
Recently, I've been exploring the driving-point impedance procedure for the derivation of double-terminated LC ladder lowpass filters. The driving-point impedance \$\text{Z}_{11}\$ for a doubly-...

Why do we typically think about circuits with nodes rather than meshes?
I was trying to wrap my head around the fact that voltages have a ground reference but currents are absolute, and yet, despite this fundamental difference, they are somehow mathematical duals of each ...
