RC circuit with DC source: Kirchhoff’s law, voltage directions, and current flow convention
I am creating a video in Manim about basic electrical circuits. The circuit under consideration is an ideal RC circuit with a DC voltage source, no energy losses. My reasoning is as follows: When the ...

Why does KCL not work in the ideal non-inverting op amp output node?
I have a simple ideal non-inverting op-amp pictured below: If I take KCL at the inverting terminal, I get (Vs - 0)/(R1) + (vs - Vo)/(R2) = 0. This gives me the proper equation of Vo = (1 + (R2/R1))(...

Assumptions in a ideal circuit which consists of ideal wires(zero resistance)
Let us say a circuit consists only of a battery and ideal wires. Assuming steady state, if we remove the battery and now complete the circuit with only ideal wires, is it safe to say that the ...

I made a 3-phase power rectifier circuit with "ideal" diodes. Is there anything I should change?
I made this 3 phase power rectifier with ideal diodes, instead of actual diodes. I basically just copied an ideal diode diagram and pasted it 6 times. It's for use on a wind turbine project, to ...

Ideal voltage vs ideal current source - which one wins?
Here is an example 5.8 from Hayt "Engineering Circuit Analysis" - 8th edition (p.146). The goal is to find Thevenin equivalent faced by 1k\$\Omega\$ resistor. I am trying to solve it using ...

Factoring in rectification voltage drop when calculating ideal DC current
Under ideal circumstances, there would be no voltage drop across a rectifier. I wanted to know if it was possible to calculate ideal DC current when a load is connected to the rectifier. For the ...

Usage of input voltages in ideal op-amp
Why is the difference between inverting and non-inverting voltages in an ideal op-amp equal to zero in many problems? I can't seem to get that. Let's say that if the difference voltage equals zero, ...
