Circuit Analysis Techniques#

Turning schematics into understanding. These techniques bridge the gap from “I see a schematic” to “I know what this node voltage should be.” They’re the analytical backbone for debugging, design review, and making sense of someone else’s circuit.

What This Section Covers#

• Series & Parallel Analysis — Equivalent R/C/L, and when simplification helps vs. hides problems.
• Voltage Dividers & Loading — The most-used circuit pattern, loading effects, and input/output impedance.
• Node & Loop Analysis — Choosing references, writing useful equations, and sanity-checking results.
• Thevenin & Norton Equivalents — Reducing complexity, bench usefulness, and limits of abstraction.
