Question 149Electricity & Electronics - 1st Asst/Chief

The correct answer is C) 10%. The color coding of the resistor bands indicates the resistance value and tolerance: - Red, violet, brown: The first three bands indicate the resistance value, which is 27,000 ohms (2,700 x 10^2). - Silver: The fourth band indicates the tolerance, which is 10%. The other answer choices are incorrect because: A) 1% is too tight of a tolerance for a standard carbon resistor. B) 5% is also a common tolerance, but not the one indicated by the silver band. D) 20% is too wide of a tolerance for this type of resistor.
