•	Yellow, violet, yellow, and silver: 47 ohms, +/- 10% tolerance.
	•	Red, red, green, and silver: 22 ohms, +/- 10% tolerance.
	•	Orange, orange, black, and gold: 33 ohms, +/- 5% tolerance.
	•	White, brown, brown, and gold: 910 ohms, +/- 5% tolerance.
	•	Brown, red, gold, and gold: 1.2 ohms, +/- 5% tolerance.

	13.	Three important factors for choosing a resistor:

	•	Resistance value (ohms).
	•	Tolerance (percentage).
	•	Power rating (watts).

	16.	The fifth color band on a precision resistor usually represents the temperature coefficient.
	17.	For red, red, red, red, red on a precision film-type resistor: 222 ohms, +/- 2% tolerance.
	18.	Carbon-composition resistors with three color bands don’t specify a tolerance rating.
	19.	A resistor with a 25-watt power rating is likely a power resistor.
	20.	A surface mount chip resistor with coding numbers 443 is 44.3 ohms.
	21.	The reliability rating on a color-coded resistor is determined by the fifth band if present. An orange fifth band typically indicates a 0.01% failure rate over 1,000 hours.
