A resistor marked with bands (yellow,voilet,orange,gold) is a 47 kOmega+-5% resistor

Any resistance measurement between $44650 \Omega$ and $49350 \Omega$ will be within the specifications.

Assuming that you just forgot the x1000 factor, the resistor is ok.

The nominal value is $R = 47$ k$\setminus \Omega$ \pm5%.

$R = 47000 \setminus \Omega \setminus \pm 2350 \setminus \Omega$.

$44650 \setminus \Omega \setminus \le q R \setminus \le q 49350 \setminus \Omega$.

#### Explanation:

1st band: yellow (4)
2nd band: violet (7)
3rd band/multiplier: orange (3)
tolerance: gold (5%)

(4)(7)\times 10^"(3)"\pm(5%) = 47k\Omega\pm 2350\Omega#

$44.68 k \setminus \Omega$ is very close to the lower limit, but still within the tolerance range.
