Schematic

Open project folder on GitHub

Demonstrates the relationship between voltage and current in an RL network.

Circuit Summary

A step input is applied to an inductor through a resistor.

Expected Behavior

  • Inductor current ramps linearly at first and approaches steady state.

How To Run

  1. Open RL-Voltage-Current.kicad_sch in KiCad.
  2. Click Simulate and run the configured analyses.
  3. Add probes to the key nodes to view the expected behavior.

Notes

  • Time constant τ = L/R controls the rise time.
