🔍 Key Concepts

• Carbon resistor color codes and what each band represents • Difference between nominal resistance value and power rating or tolerance • How resistance values are usually marked on small electronic components

💭 Think About

• Think about how very small resistors are typically labeled when there is no space for printed text—what system is used? • Which of these methods would allow you to know not just the resistance, but also its tolerance and possibly reliability class? • Ask yourself: which choice actually matches how common quarter‑watt resistors look on a circuit board?

✅ Before You Answer

• Look up how many colored bands are normally on a carbon composition or carbon film resistor and what each band means • Confirm which method is used in practice on most through‑hole resistors, not just special or large power resistors • Distinguish between markings that show resistance value versus those that show wattage (power rating) or physical size
