VIC design session v21: best candidate (Q=8.8, 98.6kHz)
Sweep — Keep f_r in the 40-70kHz band via moderate L (paired with the narrower/shorter cell C_eff from the plan) while chasing higher choke Q through lower-loss windings — fewer turns, thicker wire — since cell voltage tracks Q not L.
- Cell — 18mm rod in 24.0mm tube × 50mm, 1 cell(s) parallel → C_eff = 0.77nF, bulk water R = 18798Ω.
- Water/electrodes (Randles) — 2ppm Na+ @ 25°C, surface ×1 → λ_D 53nm, C_dl 21.2µF, cell series R 238.9Ω, displacement current 89.8%, breakdown margin ×1000+.
- Vapor-film discharge (CGDE onset, 105V across 0.1mm film) — regime constants-out-of-range, film Paschen 719V, 42 Td.
- Chokes — 2 × 0.0017H (180 turns, AWG 18, 21m wire, AC R 0.8Ω each).
- At resonance f_r = 98.58kHz — Xl = 2106Ω, Xc = 2106Ω, tank Q = 8.8, coil Q = 1335.4.
- Cell voltage 105V from 12V drive (×8.8), series current 49.9mA.
- All constraints satisfied (current <1A, band, wire length).
- Score 0.231.
