A resistance is shown in the figure. Its value and tolerance are given respectively by:
Correct Option: , 2
Solution:
(2) Color code: BI, Br, R, O, Y, G, B, V, Gr, W
$0,1,2,3,4,5,6,7,89$
$\mathrm{R}=\mathrm{AB} \times \mathrm{C} \pm \mathrm{D} \%$ where $\mathrm{D}=$ tolerance
$\mathrm{D}_{\text {gold }}=\pm 5 \%, \mathrm{D}_{\text {silver }}=\pm 10 \% ; \mathrm{D}_{\text {no colour }}=\pm 20 \%$
Red voilet orange silver
$\mathrm{R}=27 \times 10^{3} \Omega \pm 10 \%$
$\mathrm{i}=27 \mathrm{k} \Omega \pm 10 \%$
