EEE U111 · Narrated walkthrough · Module 3 §3.2
An RL circuit with two switches
Why an inductor's current cannot jump, why it becomes a wire in steady state, and the one-line formula (start, final, τ), used twice, with the clock restarted when the second switch closes. It ends with Q2 of the March 2025 mid-sem (20 marks). Press play, keep the sound on, and answer the three questions it stops to ask you.
About seven minutes, watch once (use ⏮ ⏭ to replay a scene). The narration stops to ask what the next move is. Commit to an answer before it continues: those pauses are the point, because they practise starting a question, not following one. Captions are on by default; the full transcript is below the player.
Transients in writing: the Module 3 lesson and Module 3 notes (first-order recipe, two switching events). Then redo Q2 on paper: two intervals, three numbers each.
