Assume the four observed bands are read left to right as yellow, violet, red, and gold. In a four-band format, the first two positions are significant digits, the third is multiplier, and the fourth is tolerance. The calculation identifies the selected marking only; it does not verify a physical part or its power rating.

Turn digits and multiplier into ohms

Yellow contributes 4 and violet contributes 7, producing significand 47. Red as the multiplier band means 10². Therefore 47 × 10² = 4700 Ω, which formats exactly as 4.7 kΩ. Gold is not part of the nominal resistance; it supplies the separate ±5% tolerance.

Calculate the ±5% range exactly

Five percent of 4700 Ω is 4700 × 5 ÷ 100 = 235 Ω. Subtracting gives 4465 Ω and adding gives 4935 Ω. Thus the nominal tolerance range is 4465–4935 Ω. It is not a guarantee of the current measured value or safe use in a circuit; those require the actual component and datasheet context.
