To determine the resistance indicated by the color code of Orange, White, Silver, and a Gold band, we need to decode the color bands first. The first two colors correspond to digits, while the third color represents a multiplier, and the fourth band indicates tolerance.

  1. Orange corresponds to the digit 3.
  1. White corresponds to the digit 9.

  2. Silver indicates a multiplier of 0.01 (which means we will multiply our number by a factor of 0.01).

Putting the digits together, Orange (3) and White (9) gives us the number 39. Now applying the multiplier of Silver (0.01):

39 * 0.01 = 0.39 Ohms

The Gold band indicates the tolerance level of the resistor, but this does not affect the ohmic value calculated from the color codes. Hence, the correct interpretation of the color bands leads us to a resistance of 0.39 Ohms.
