70% to pass

A carbon resistor has the following color bands; band 1 is yellow, band 2 is violet, band 3 is yellow, and band 4 is silver. What is the value of the resistor in ohms, as well as the tolerance? Illustration EL-0103

Diagram for USCG Electrical Chief: A carbon resistor has the following color bands; band 1 is yellow, band 2 is...
A74 ohms + or - 5%
B4,700 ohms + or - 10%
C74,000 ohms + or - 5%
D470,000 ohms + or - 10%
AI Explanation

The correct answer is D) 470,000 ohms + or - 10%. To determine the value of the resistor, we need to interpret the color bands according to the standard resistor color code. The first two bands represent the first two digits of the resistance value, while the third band represents the multiplier. The fourth band indicates the tolerance. In this case, the color bands are yellow (4), violet (7), and yellow (4), which translates to a resistance value of 470,000 ohms. The silver fourth band indicates a tolerance of +/- 10%. The other options are incorrect because they do not correctly interpret the color bands or the tolerance value.
