Question

Find the colour code for the following value of resistor having tolerance ± 10%.

i. 330 Ω 

ii. 100 Ω 

iii. 47 kΩ 

iv. 160 Ω 

v. 1 kΩ

Answer 1

	Value of resistance	1st Band	2nd Band	Multiple	Tolerence	Colour code
i.	330 Ω ± 10% = 33 × 101Ω ± 10%	3 (Orange)	3 (Orange)	101 (Brown)	± 10% (Silver)	Orange-Orange-Brown-Silver
ii.	100 Ω ± 10% = 10 × 101Ω ± 10%	1 (Brown)	0 (Black)	101 (Brown)	± 10% (Silver)	Brown-Black-Brown-Silver
iii.	47 Ω ± 10% = 47 × 103​​​​​​​Ω ± 10%	4 (Yellow)	7 (Violet)	103 (Orange)	± 10% (Silver)	Yellow-Violet-Orange-Silver
iv.	160 Ω ± 10% = 16 × 101​​​​​​​Ω ± 10%	1 (Brown)	6 (Blue)	101 (Brown)	± 10% (Silver)	Brown-Blue-Brown-Silver
v.	1 Ω ± 10% = 10 × 102​​​​​​​Ω ± 10%	1 (Brown)	0 (Black)	102 (Red)	± 10% (Silver)	Brown-Black-Red-Silver
