// WHAT YOU WILL LEARN

M = mega = × 1,000,000, so 1 MΩ = 1,000,000 ohms (brown-black-green).

// LESSON NOTES

Quick quiz: what does the 'M' mean in 1 MΩ? 🤔🔢

A) × 1,000
B) × 1,000,000
C) milli
D) maximum

✅ B! Capital M = MEGA = × 1,000,000 (a million).
🔢 So 1 MΩ = 1,000,000 Ω (ohms). Ladder: 1 Ω → 1 kΩ (× 1,000) → 1 MΩ (× 1,000 again).
🎨 On the resistor: brown (1) · black (0) · GREEN (× 100,000) · gold (± 5 %) → 10 × 100,000 = 1,000,000.
⚡ Same 'M' as in MW (megawatt) and MHz (megahertz).
⚠️ Careful: small m is something very different!
