// WHAT YOU WILL LEARN

Power off and take the part out of the circuit, then read ohms; compare with the colour code and its tolerance.

// LESSON NOTES

Your 1 kΩ resistor reads 500 Ω? 😱 Your meter isn't broken!

🔌 It's still in the circuit — another part gives the test current a second path (1 kΩ + 1 kΩ side by side = 500 Ω).
1️⃣ Power OFF and lift one leg out.
2️⃣ Don't hold both metal tips — your body is a path too!

✅ Now it reads 980 Ω: brown-black-red-gold = 1 kΩ ±5 % → anything from 950 to 1,050 Ω is good.

Read the voiceover (transcript)
  1. Why does this one k resistor read only five hundred?
  2. It's still in the circuit! Another part shares the path.
  3. Rule one: power off, and take one leg out.
  4. Rule two: don't hold both probes. Your body is a path too!
  5. So what should it read now?
  6. Nine eighty ohms!
  7. Inside five percent of one k. Good!
  8. Next: measure current, the meter goes in the circuit! Follow for Part six!
