How two plates store charge (Q = CV), why area and gap and a dielectric set the capacitance (C = ε₀εᵣA/d), how capacitors add in series and parallel, the energy locked in a charged capacitor (½CV²), and the charge–discharge curve. Read the full lecture, watch each idea fill and empty on screen, then run the virtual experiment. Pick any door — they all teach the same chapter.
Read it, fill the plates with charge, then check yourself.
