For questions about ground loops, which occur when multiple ground nodes in a circuit (which should be at the same potential) actually have a potential difference between them. This is usually caused by a significant current flowing between the ground node(s), thus producing a voltage between them. Ground loops cause various problems in a circuit.

Ground loop via pull-down resistor
I'm developing an STM32-based device, one of whose functions is to periodically monitor the main power 12V battery voltage.
I created a simple switching circuit with a voltage divider. I have added a …
