Direct Current Circuits – Kirchhoff’s Rules & Applications Explained | Chapter 26 of University Physics
Direct Current Circuits – Kirchhoff’s Rules & Applications Explained | Chapter 26 of University Physics Chapter 26 builds on basic circuit concepts to tackle complex DC networks using Kirchhoff’s rules. You’ll learn how to analyze resistor combinations beyond simple series and parallel, see how ammeters and voltmeters are properly connected, explore the transient behavior of RC circuits, and understand real‐world power distribution in homes and vehicles. Watch the full video summary here for detailed problem‐solving examples. Resistors in Series & Parallel Understanding simple combinations is the first step: Series: Same current flows through each resistor; R eq = R₁ + R₂ + … ; voltages add. Parallel: Same voltage across each branch; 1/R eq = 1/R₁ + 1/R₂ + … ; currents divide inversely by resistance. Kirchhoff’s Rules for Complex Circuits When networks can’t be simplified, apply: Junction Rule: ∑I in = ∑I out (charge conservation). Loop Rule: ...
