Inductance Topic

Demonstrates how mechanical interruption of DC current produces high-voltage pulses through electromagnetic induction. Students see why transformers require changing current — steady DC produces no induced EMF — and observe …

Students observe inductive transients in an RL circuit: the incandescent bulb flashes brightly each time the knife switch opens or closes, revealing current surges during magnetic field buildup and collapse. …

Demonstrates underdamped oscillations in a series RLC circuit driven by a square wave. Students observe the "ringing" waveform — damped sinusoidal oscillations at the circuit's natural frequency — and connect …
