Yellow, violet, black,gold

Yellow-4 .    Violet-7    Black-10*0=1 gold=±5%

Clarification - first and second show significant. Third show Multiplier and last show tolerance. And we know that any number have 0 power then the value will be-

47×1+-4.7

Hey ,

According to the question ,

R = (47 ± 4.7) x 10 3

R = 47 x 103  ± 10% Ω
As per color code, 3 - Orange, 4 - Yellow, 7 - Violet, 10% - Silver

Thank you !
