Question #e412f

Answer 1

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

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

Answer 2

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

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

`R = 47000\Omega \pm 2350\Omega`.

`44650\Omega \leq R \leq 49350 \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\Omega` is very close to the lower limit, but still within the tolerance range.
