Evaluate resistance for the following colour coded resistors: i. Yellow – Violet – Black – Silver 

i. Given: Yellow – Violet – Black – Silver

To find: Value of resistance 

Formula: Value of resistance

= (xy × 10^z ± T%)Ω

Colour	Yellow (x)	Violet (y)	Black (z)	Sliver (T%)
Code	4	7	0	±10

Hence x = 4, y = 7, z = 0, T = 10%

Value of resistance = (xy ×10^z ± T%) Ω

= (47 × 10° ± 10%) Ω

Value of resistance = 47 Ω ± 10%

To find: Value of resistance

Formula: Value of resistance

= (xy × 10^z ± T%) Ω

Calculation:

Colour	Green (x)	Blue (y)	Red (z)	Gold (T%)
Code	5	6	2	±5

Hence x = 5, y = 6, z = 2, T = 5%

Value of resistance = (xy × 10^z ± T%) Q

= 56 × 102 Ω ± 5%

= 5.6 k Ω ± 5%

iii. Given: Brown – Black – Orange – Gold

To find: Value of the resistance

Formula: Value of the resistance

= (xy × 10^z ± T%) Ω

Calculation:

Colour	Brown (x)	Black (y)	Orange (z)	Gold (T%)
Code	1	0	3	±5

Hence x = 1, y = 0, z = 3, T = 5%

Value of resistance = (xy × 10^z ± T%) Ω

= 10 × 10³ Ω ± 5%

= 10 kΩ ± 5%
