Answers to Resistor Questions

The Questions to these answers can be found here.

a);

Red (1st Significant Figure): 2 

Red (2nd Significant Figure): 2

Red (Multiplier): (10²) = (100)

Gold (Tolerance): ±5%

So, the resistor’s value is (22 x 100 Ω, Or 2.2 KΩ) with a tolerance of ±5%.

b);

Brown (1st Significant Figure): 1 

Black (2nd Significant Figure): 0  

Grey (Multiplier): (10⁸) = (100,000,000)

Silver (Tolerance): ±10%

So, the resistor’s value is (10 x 10⁸ Ω, Or 1GΩ) with a tolerance of ±10%

c);

Yellow (1st Significant Figure): 4

Violet (2nd Significant Figure): 7

Orange (Multiplier): (10⁴) = (10,000)

Red (Tolerance): ±2%

So, the resistor’s value is (47 x 10⁴ Ω, Or 470 KΩ) with a tolerance of ±2%

d);

(Notice this resistor is a 5 band resistor)

Grey (1st Significant Figure): 8

Green (2nd Significant Figure): 5

Black (3rd Significant Figure): 0

Orange (Multiplier): (10³) = (1000)

Gold (Tolerance): ±5%

So, the resistor’s value is (850 x 10³ Ω, Or 850 KΩ) with a tolerance of ±5%

e);

(Notice this is also a 5 band resistor)

Orange (1st Significant Figure): 3

Red (2nd Significant Figure): 2

Black (3rd Significant Figure): 0

Brown (Multiplier): (10¹) = (10)

Red (Tolerance): ±2%

So, the resistor’s value is (320 x 10 = 3200 Ω Or 3.2 KΩ) with a tolerance of ±2%
