Question
Colour code of resistor is Yellow-Violet- Orange-Gold. Find its value.
✓

Answer

  Yellow (x) Violet (y) Orange (z) Gold (T%)
 Value 4 7 3  $\pm 5$
Value of resistance: $x y \times 10^z \Omega \pm$ tolerance
$\therefore$ Value of resistance $=47 \times 10^3 \Omega \pm 5 \%$
$=47 k \Omega \pm 5 \%$
