If you need a 5.1 Ω resistor with +/- 5% tolerance, what color code should you look for?

Answer 1

We know For resistor colour coding.

COLOUR	digit1	digit2	multiplier	tolerance (%)
Black	0	0	10^0
Brown	1	1	10^1	1
Red	2	2	10^2	2
Orange	3	3	10^3
Yellow	4	4	10^4
Green	5	5	10^5	0.5
Blue	6	6	10^6	0.25
Violet	7	7	10^7	0.1
Grey	8	8	10^8
White	9	9	10^9
Gold			10^-1	5
Silver			10^-2	10

For 5.1 ohm and +/- 5% toralence we have to choose the below colour coding

Green,brown, gold,gold. (51×10^-1 +/-5%)
