193. 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

The resistor value is determined by the color bands: yellow (4), violet (7), yellow (multiplier of 10,000), and silver (+-10% tolerance). This results in a resistance of 47 x 10,000 ohms, or 470,000 ohms with a +-10% tolerance.
