To determine the resistance value of a resistor based on its color stripes, each color corresponds to a specific number and a certain tolerance. For the resistor with the stripes yellow, violet, violet, and silver:

  • The first stripe (yellow) corresponds to the digit 4.
  • The second stripe (violet) represents the digit 7.

  • The third stripe (violet) in the context of a three-band resistor signifies the number of zeros to add, which indicates a multiplier of 100 (or two additional digits).

This means that the value calculated from the digits is 47, and when applying the multiplier of 100, the final value becomes 4700 Ohms, which can also be expressed as 4.7 KOhm.

Now, analyzing the tolerance indicated by the last stripe: silver indicates a tolerance of +/- 10%.

However, it’s essential to note that the interpretation in the question relies on the correct placement of the decimal point. The proper reading should lead to a value that effectively correlates with the accepted options given the color coding.

The value derived from the stripe reading thus corresponds to 470 Ohms or 470 KOhm in different contexts, but when considering the nature of electronic components
