Series-Parallel Circuit Analysis

Run in fullscreen

Description

This MicroSim presents a series-parallel resistor network and walks through the systematic reduction to a single equivalent resistance. Adjust individual resistor values and observe how voltages and currents throughout the network update. The step-by-step reduction panel on the side explains each simplification, bridging the gap between the two basic topologies.

Key Concepts

  • Series-parallel circuits combine both topologies; reduction works by repeatedly collapsing parallel groups then series strings.
  • Identify parallel sub-groups first, replace with \(R_{eq}\), then combine results in series.
  • Node voltages and branch currents satisfy both KVL and KCL simultaneously.
  • The same source voltage drives different currents through different paths.
  • This technique extends to arbitrarily complex resistive networks by repeated application.
