E12 sensor valuesE12 sensor values. C1: capacitor, 220 nF. R1: resistor, 4.7 kΩ. ground: C1.b connected to GND. input: R1.a connected to VIN. output: C1.a connected to R1.b connected to VOUT. fc = 1/(2πRC) = 154 Hz. Ideal first-order model. Not a simulation or an electrical-safety assessment.. Focus components: none. Focus nets: output.

Scroll horizontally on smaller screens to inspect legible nodes and labels. No simulation is performed.

The original input stays intact, including invalid fields.

Expected vs. actual

An inspectable result.

These checks compare the renderer outcome with the declared case expectation. The stress test also checks determinism, geometry, and connectivity.

Electrical nodes & connectivity

Each net is one electrical node: the named endpoints below are connected. Component pins and external ports are endpoints. These counts are not the number of geometric junction dots or wire bends. No voltages, currents, or simulation results are inferred.
