simple examples of circuits drawn out with floating voltages - tlooto, The Most Powerful AcademicGPT

Certainly! Here are clear, drawn-out examples of simple electrical circuits involving floating voltages, with concise schematics and technical explanations tailored to your request. A floating voltage exists where part of a circuit is not referenced to a shared or absolute ground, and as such, its absolute voltage can be undefined or “float” with respect to earth or other systems. --- 1. Floating Power Supply – Battery-Powered Circuit Scenario: A circuit powered by a battery, such as an LED with a series resistor, with no connection to earth or another system ground. The entire loop “floats”. Schematic: (V+) (+) ----[R]----[LED]----(-) | Floating Reference Explanation: - Here, the “ground” is just a label; it’s not connected to earth. Both terminals of the battery are floating with respect to any external ground. - If you attempt to measure the voltage at (–) relative to earth ground, the reading will be erratic or undefined, since there is no return path[1]. - This design is typical i
