Parallel RLC, from basics to Mar 2025 Q3
A narrated lesson on the parallel RLC circuit, the twin of the series one: the elements share a voltage, so the starting slope comes from KCL and α = 1/(2RC). It solves the 20-mark past-paper question end to end: v(0⁺), dv/dt(0⁺), v(t), and the plot. Press play, keep the sound on, and answer the four questions it stops to ask you.
About eight minutes, watch once (use ⏮ ⏭ to replay a scene). The narration stops four times 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. The series RLC walkthrough explains the characteristic equation more slowly; watch it first if this is your first second-order circuit.
Close the page and redo Q3 on paper, including the sketch for part (c): envelope first, then the landmarks. The written method is in the Module 3 lesson and notes; the full paper is on the mid-sem past papers page.
