## Sample questions resistor color code

1. What is the value of the electrical resistance of the resistor with color rings as follows:

a. Yellow, purple, red, and gold

b. orange, white, brown, and gold

c. green, blue, yellow, and silver

d. brown, black, green, and colorless

e. red, red, red, and gold

2. What color rings on the body of the resistor, the value of resistance mentioned below (ignoring the value of tolerance)?

a. 33 Ω; b. 200 kΩ; c. 750 Ω; d. 43 kΩ; e. 1.2 MΩ

purple = 7

red = 2

gold = ± 5%

write '4 'and '7', then follow these two numbers with 2 digits '0 '. The results obtained are 4700 Ω or 4.7 kΩ with a tolerance ± 5%

b. orange = 3

white = 9

brown = 1

gold = ± 5%

results obtained is 390 Ω with a tolerance ± 5%

c. Green = 5

blue = 6

yellow = 4

Silver = ± 10%

results obtained are 560,000 Ω or 560 kΩ with a tolerance ± 10%

d. brown = 1

black = 0

Green = 5

colorless = ± 20%

results obtained are 1000000 Ω or 1 MΩ with tolerance ± 20%

e. red = 2

red = 2

red = 2

gold = ± 5%

results obtained is 2200 or 2.2 kΩ with a tolerance ± 5%

3 is orange

3 is orange

0 is black

So ring colors are orange, orange, black.

b. 200 kΩ = 200,000 Ω = 20 x 10

2 is red

0 is black

4 is yellow

So ring the colors are red, black, yellow.

c. 750 Ω = 75 x 10

7 is purple

5 is green

1 is brown

So ring colors are purple, green, brown.

d. 43 kΩ = 43,000 = 43 x 10

4 is yellow

3 is orange

3 is orange

So ring colors are yellow, orange, orange.

e. 1.2 MΩ = 1200 kΩ = 1,200,000 Ω = 12 x 10

1 is brown

2 is red

5 is green

So ring colors are brown, red, green.

a. Yellow, purple, red, and gold

b. orange, white, brown, and gold

c. green, blue, yellow, and silver

d. brown, black, green, and colorless

e. red, red, red, and gold
